maxim integrated 11 table 1. current-limit type select detailed description the max14588 is an adjustable overvoltage and over - current protection device designed to protect systems against positive and negative input voltage faults up to 40v, and features a low 190m (typ) on-resistance fet. if the input voltage exceeds the ovlo threshold or falls below the uvlo, the internal fets are turned off to prevent damage to the protected components. if the ovlo or the uvlo pin is set below the external ovlo or uvlo select threshold (v sel_ovlo , v sel_uvlo ), the device automatically selects the internal 5% accurate trip thresholds. the internal ovlo threshold is preset to 33v (typ), and the internal uvlo threshold is preset to 19v (typ). current-limit type select the max14588 power-up current-limit default is continu - ous mode when clts_mode is low. after power up, the current-limit type can be programmed externally through clts1 and clts2 (table 1). when clts_mode is high, clts1 and clts2 are sampled continuously. when clts_mode is low, clts1 and clts2 are sampled only when v in -v out < 0.6v. connect clts1, clts2, and clts_mode to clhs for logic-high or to gnd for logic-low. autoretry when the current threshold is reached, the t blank timer begins counting. the flag asserts if the overcurrent con - dition is present for t blank . the timer resets if the over - current condition disappears before t blank has elapsed. a retry time delay, t retry , is started immediately after t blank has elapsed and during t retry time, the fets are off. at the end of t retry , the fets are turned on again. if the fault still exists, the cycle is repeated and the flag stays low. when the fault is removed, the fets stay on. (figure 1) the autoretry feature reduces the system power in case of overcurrent or short-circuit conditions. during t blank time, when the switch is on, the supply current is held at the current limit. during t retry time, when the switch is off, there is no current through the switch. thus, the output current is much less than the programmed current limit. calculate the average output current using the fol - lowing equation. blank load lim blank retry t ii tt ?? = ?? + ?? with a 21ms (typ) t blank and 620ms (typ) t retry , the duty cycle is 3.3%, resulting in a 96.7% power saving. latch-off when the current threshold is reached, the t blank timer begins counting. the flag asserts if the overcurrent condition is present for t blank . the timer resets when the overcurrent condition disappears before t blank has elapsed. the switch turns off and stays off if the over - current condition continues beyond the blanking time. to reset the switch, either toggle the control logic en or hven or cycle the input voltage. (figure 2) continuous when the current threshold is reached, the max14588 limits the output current to the programmed current limit. the flag asserts if the overcurrent condition is present for t blank and deasserts when the overload condition is removed. (figure 3) reverse-current block enable (rien) this feature disables the reverse-current protection and enables reverse-current flow from out to in. the reverse- current block enable feature is useful in applications with inductive loads. fault flag output flag is an open-drain fault indicator output and requires an external pull-up resistor to a dc supply. flag goes low when any of the following conditions occur: the blanking time has elapsed the reverse-current protection has tripped the die temperature exceeds +150oc seti is connected to ground ovlo threshold is reached clts2 clts1 current-limit type 0 0 latch off 0 1 autoretry 1 0 continuous 1 1 continuous max14588 1a adjustable overcurrent and overvoltage protector with high accuracy www.maximintegrated.com
maxim integrated 12 thermal shutdown protection the max14588 has a thermal-shutdown feature to pro - tect the device from overheating. the device turns off and the flag asserts when the junction temperature exceeds +150oc (typ). the devices exit thermal shutdown and resume normal operation after the junction temperature cools by 30oc (typ), except when in latch off mode, the device remains latched off. the thermal limit behaves similar to the current limit. for autoretry mode, the thermal limit works with auto retry timer. when the device comes out of the thermal limit, it starts after the retry time. for latch off mode, the device latches off until power or en cycle. for continuous mode, the device only disables while the temperature is over the limit. there is no blanking time for thermal protection. overvoltage lockout (ovlo) the max14588 has a 33v (typ) preset ovlo threshold when the voltage at ovlo is set below the external ovlo select voltage (v sel ). connect ovlo to gnd to activate the preset ovlo threshold. connect the external resistors to ovlo pin as shown in the typical operating circuit to externally adjust the ovlo threshold. use the following equation to adjust the ovlo threshold. the rec - ommended value for r3 is 2.2m. ovlo bg r3 v v1 r4 ?? = + ?? ?? undervoltage lockout (uvlo) the max14588 has a 19v (typ) preset uvlo threshold when the voltage at uvlo is set below the external ovlo select voltage (v sel ). connect uvlo to gnd to activate the preset uvlo threshold. connect the external resistors to uvlo pin as shown in the typical operating circuit to externally adjust the uvlo threshold. use the following equation to adjust the uvlo threshold. the recommend - ed value for r1 is 2.2m. uvlo bg r1 v v1 r2 ?? = + ?? ?? switch control there are two independent enable inputs ( hven and en) for max14588. hven is a high-voltage capable input. toggle hven or en to reset the fault condition once short-circuit is detected and the device shuts down (table 2). input debounce protection the max14588 features input debounce protection. when the input voltage is higher than the uvlo thresh - old voltage for a period greater than the debounce time (t deb ), the internal fets are turned on. this feature is intended for applications where the en or hven signal is present when the power supply ramps up (figure 3). applications information setting the current limit / threshold a resistor from seti to ground programs the current-limit/ threshold value for the max14588. leaving seti uncon - nected selects a 0a current limit/threshold. connecting seti to ground asserts flag . use the following formula to calculate the current limit: 6100 r (k ) seti i (ma) lim ?= in bypass capacitor connect a minimum of 0.47f capacitor from in to gnd to limit the input voltage drop during momentary output short-circuit conditions. larger capacitor values further reduce the voltage undershoot at the input. hot plug in in many system powering applications, an input filter - ing capacitor is required to lower the radiated emission, enhance the esd capability, etc. in hot plug applications, parasitic cable inductance along with the input capacitor causes overshoot and ringing when the powered cable is connected to the input terminal. this effect causes the protection device to see almost twice the applied voltage. an input voltage of 24v can easily exceed the absolute maximum rating of 40v, which may permanently damage the device. a transient voltage suppressor (tvs) is often used for industrial applications to protect the system from these conditions. we recom - mend using a tvs that is capable of limiting the input surge to 40v placed close to the input terminal. table 2. enable inputs hven en switch status 0 0 on 0 1 on 1 0 off 1 1 on max14588 1a adjustable overcurrent and overvoltage protector with high accuracy www.maximintegrated.com
maxim integrated 13 out bypass capacitor for stable operation over the full temperature range and over the entire programmable current-limit range, con - nect a 4.7f ceramic capacitor from out to ground. excessive output capacitance can cause a false overcur - rent condition due to decreased dv/dt across the capaci - tor. calculate the maximum capacitive load (c max ) value that can be connected to out by using the following formula: lim blank (typ) max i (ma) x t (ms) c (f) v (v) in = for example, for v in = 24v, t blank(typ) = 20ms, and i lim = 1a, c max equals 833f. output freewheeling diode for inductive hard short to ground in applications that require protection form a sudden short to ground with an inductive load or a long cable, a schottky diode between the out terminal and ground is recom - mended. this is to prevent a negative spike on the out due to the inductive kickback during a short-circuit event. layout and thermal dissipation to optimize the switch response time to output short- circuit conditions, it is very important to keep all traces as short as possible to reduce the effect of undesirable parasitic inductance. place input and output capacitors as close as possible to the device (no more than 5mm). in and out must be connected with wide short traces to the power bus. during normal operation, the power dissipa - tion is small and the package temperature change is mini - mal. if the output is continuously shorted to ground at the maximum supply voltage, the switches with the autoretry option do not cause thermal shutdown detection to trip: in(max) out(max) blank retry blank vi t p (max) t t = + attention must be given to continuous current-limit mode when the power dissipation during a fault condition can cause the device to reach the thermal shutdown threshold. thermal vias from the exposed pad to ground plane are highly recommended to increase the system thermal capac - itance while reducing the thermal resistance to the ambient. max14588 1a adjustable overcurrent and overvoltage protector with high accuracy www.maximintegrated.com
