general description the MAX16132Cmax16135 are low-voltage, 1% accurate, single, dual, triple, and quad-volt age p supervisors that monitor up to 4 system-supply voltages for undervoltage and overvoltage faults. the MAX16132Cmax16134 feature independent reset outputs, while the max16135 features dual reset outputs. for the MAX16132Cmax16134, a reset output asserts when the voltage at its corresponding input falls outside a factory-trimmed undervoltage and overvoltage window threshold. the reset is maintained for a minimum timeout period after voltage at the input falls within the factory-set window threshold. for the max16135, a reset output asserts when either, or both, of the corresponding inputs fall outside the factory-trimmed undervoltage and overvoltage window thresholds. see selector guide for available options. these integrated supervisory circuits significantly improve system reliability and reduce size compared to separate ics or discrete components. the MAX16132Cmax16135 are fixed-threshold devices. the nominal input voltage for any input is factory programmable from 0.5 to 5.0v, providing a wide range of threshold selections. the window threshold levels are factory programmable from 4% to 11%, with 1% resolution and 0.25% or 0.50% hysteresis. the 1% threshold accuracy over temperature and window threshold monitoring make these devices ideal for automotive adas applications. the reset outputs are active-low, open-drain, and are guaranteed to be in the correct reset output logic state when v dd remains greater than 1.0v. all devices are offered with 23 reset timeout periods ranging from 20s (min) to 1200ms (min). all reset outputs share the same factory-set reset timeout period. the MAX16132Cmax16135 are available in a small 8-pin sot23 package and specified over the automotive temperature range of -40c to +125c. applications adas multivoltage asics storage equipment servers ordering information appears at end of data sheet. 19-8708; rev 0; 11/16 benefts and features high precision ? 1% threshold accuracy over temperature programmable ov threshold: 104% to 111% programmable uv threshold: 89% to 96% programmable input voltage from 0.5v to 5.0v low 15a supply current quad-input monitor 23 programmable reset timeout periods immune to short monitored supply transients guaranteed correct logic state down to v dd = 1v open-drain outputs small sot-23 package -40c to +125c automotive operating temperature range MAX16132Cmax16135 low-voltage, precision, single/dual/triple/ quad-voltage p supervisors evaluation kit available

detailed description detailed description the MAX16132Cmax16135 are single, dual, triple, and quad-voltage p supervisors designed to maintain system integrity in multi-supply systems. these devices offer undervoltage and overvoltage window threshold monitoring within 1% accuracy over temperature. input voltage the MAX16132Cmax16135 feature factory-programmable input-voltage-level options from 0.5v to 5v. see table 1 thru table 4 , as well as the selector guide for standard voltage options. the selection of nominal input voltage does not set the voltage threshold levels. for the MAX16132C max16135, the undervoltage and overvoltage thresholds are determined by the selection of input tolerance.see the electrical characteristics table and input tolerance/ hysteresis section for more detail. input tolerance/hysteresis the MAX16132Cmax1635 are designed to offer eight factory-programmable input tolerance levels from 4% to 11% in 1% increments. the input tolerance level sets the undervotlage and overvoltage threshold levels with respect to the selected nominal input voltage. see table 5 thru table 8 for hysteresis and tolerance values. the MAX16132Cmax16135 are immune to short in_ transients. each of the internal comparators are factory set to either 0.5% or 0.25% hysteresis with respect to the selected nominal input voltage. hysteresis provides input immunity to ambient noise without significantly reduc - ing the input threshold accuracy. see the maximum in_ transient duration vs. reset threshold overdrive graph in the typical operating characteristics section . reset outputs the MAX16132Cmax16134 feature independent, active- low, open-drain reset outputs, while the max16135 features dual reset outputs. for the MAX16132Cmax16134, when an input voltage falls outside the set window threshold, the corresponding reset outputs asserts. the reset output de-asserts after the reset timeout period when the input voltage falls within the window threshold. see figure 1 for more detail. the max16135 feature dual reset outputs. reset1 asserts when v in1 and/or v in2 falls outside the set window threshold. reset2 asserts when v in3 and/or v in4 falls outside the set window threshold. reset1 and reset2 de-assert after the reset timeout period when their corresponding input voltages are within the set win - dow threshold. at power-up, resets stay asserted for the reset timeout period once v dd is above the uvlo. all reset outputs require a pullup resistor to v dd . figure 1. independent reset output timing diagram (max16133/max16134) maxim integrated 15 www.maximintegrated.com MAX16132Cmax16135 low-voltage, precision, single/dual/triple/ quad-voltage p supervisors

applications information unused inputs the MAX16132Cmax16135 are capable of monitoring inputs for undervoltage and overvoltage events within a very narrow voltage window. connect any unused in_ input to its nominal voltage setting. setting input thresholds the MAX16132Cmax16135 reset devices that monitor input within a window-threshold set by the input tolerance selection. tolerance setting determines the boundary for undervoltage and overvoltage thresholds. the selected nominal input voltage must stay within the window threshold for the MAX16132Cmax16135 not to issue a reset signal. see below for threshold calculation for 2.5v nominal input voltage and 10% input tolerance: v innom = 2.5v tol = 10 % v uvth = v innom ( 1 ? 10 % ) = 2.5v ( 1 ? 0.1 ) = 2.5v ? 0.250v = 2.250v v ovth = v innom ( 1 + 10 % ) = 2.5v ( 1 + 0.1 ) = 2.5v + 0.250v = 2.750v where v innom is the selected nominal input voltage, tol is the input tolerance, v uvth is undervotlage threshold voltage and v ovth is the overvoltage threshold voltage. the MAX16132Cmax16135 feature 1% threshold accuracy over temperature. this excursion must be added to the calculated undervotlage and overvoltage threshold settings to account for the threshold variation as shown below: v uvth_exc = v uvth ( 1 1 % ) = 2.250v ( 1 0.01 ) = 2.250v 0.0225v v ovth_exc = v ovth ( 1 1 % ) = 2.750v ( 1 0.01 ) = 2.750v 0.0275v where v uvth_exc is the undervoltage threshold variation and v ovth_exc is the overvoltage threshold variation. undervoltage/overvoltage-detection circuit the open-drain outputs of the MAX16132Cmax16135 can be configured to detect an undervoltage/overvoltage condition. figure 2 shows the max1632 reset output deriving the gate of a pfet low to turn on an led when there is an overvoltage/undervoltage event on in. figure 2. undervoltage/overvoltage detection circuit with led indicator maxim integrated 19 www.maximintegrated.com MAX16132Cmax16135 low-voltage, precision, single/dual/triple/ quad-voltage p supervisors
power-supply bypassing and grounding the MAX16132Cmax16135 operate from a 1.71v to 5.5v supply. an undervoltage lockout ensures that the outputs are in the correct states when the uvlo is exceeded. bypass v dd to ground with a 0.1f capacitor as close to the device as possible. additional capacitor improves transient immunity. for fast transients with large volt - age excursion, a filter resistor in series with the bypass capacitor is recommended for proper device operation. see figure 3 below for more detail. figure 3. power supply bypassing/input filter typical operating circuit *: denotes optional filter resistor in series with the input bypass capacitance. for a transient excursion of 1.71v v dd 5.5v a 500 is recommended. maxim integrated 20 www.maximintegrated.com MAX16132Cmax16135 low-voltage, precision, single/dual/triple/ quad-voltage p supervisors
