general description the max4881?ax4884/max4893b overvoltage pro- tection (ovp) controllers with built-in current-limited switch, protect low-voltage systems against voltages of up to 28v. when the input voltage exceeds the overvolt- age trip level of 5.6v (max4881/max4883 /max4893b) or 4.5v (max4882/max4884), the external n-channel mos- fet is turned off to prevent damage to the protected components. an undervoltage/overvoltage flag indicator ( ov ) notifies the processor that an undervoltage/overvolt- age fault condition is present. the max4881/max4882 feature an internal 1.1a current-limited switch, while the max4883b/max4883c/ max4884b/max4884c include an internal 0.7a current- limited switch. the max4893b includes a 0.9a current- limited switch. when the load current is at the current limit for longer than the blanking time, the switch of the max4881/max4882/max4883b/max4884b/ max4893b latches off and does not turn back on until en, cb, or in is cycled. a current-limit flag ( flagi ) asserts to indicate a current fault condition. the max4883c/max4884c limit the current to 0.7a indefinitely until the thermal protection trips. an overcur- rent flag output asserts to indicate a current fault condi- tion after the blanking time has elapsed. the max4881?ax4884/max4893b have a control input (cb) that is used to turn on and off the internal cur- rent-limited switch. other features include a shutdown function ( en ) to disable the external n-channel mosfet, and a built-in startup delay to allow the adapter voltage to settle down before turning on the mosfet. the max4881?ax4884/max4893b are offered in a space-saving 10-pin tdfn package and operate over the extended -40? to +85? temperature range. applications features overvoltage protection up to 28v preset overvoltage trip level 5.6v (max4881/max4883/max4893b) 4.5v (max4882/max4884) internal current-limited switch 1.1a (max4881/max4882) 0.7a (max4883/max4884) 0.9a (max4893b) drives low-cost n-channel mosfet internal 50ms startup delay overvoltage fault ov indicator current-limit fault flagi indicator undervoltage lockout thermal shutdown protection tiny 10-pin tdfn package max4881?ax4884/max4893b overvoltage protection controllers with current limit in tdfn ________________________________________________________________ maxim integrated products 1 ov flagi gnd btb max4881 max4882 max4883 max4884 max4893b n.c. in gate bta en 3mm x 3mm tdfn top view cb 134 10 *ep *connect exposed pad to gnd. 87 2 9 5 6 + pin configuration ordering information 19-3777; rev 2; 10/06 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. part temp range pin-package ov trip level (v) current limit (a) current-limit mode top mark pkg code max4881 etb -40 c to +85 c 10 tdfn-ep* 5.6 1.1 latchoff apk t1033-1 max4882 etb -40 c to +85 c 10 tdfn-ep* 4.5 1.1 latchoff apl t1033-1 max4883b etb -40 c to +85 c 10 tdfn-ep* 5.6 0.7 latchoff apm t1033-1 max4883cetb -40 c to +85 c 10 tdfn-ep* 5.6 0.7 continuous apn t1033-1 max4884b etb** -40 c to +85 c 10 tdfn-ep* 4.5 0.7 latchoff apo t1033-1 max4884cetb** -40 c to +85 c 10 tdfn-ep* 4.5 0.7 continuous app t1033-1 max4893b etb -40 c to +85 c 10 tdfn-ep* 5.6 0.9 latchoff atf t1033-1 cell phones digital still cameras pdas and palmtop devices mp3 players * ep = exposed pad. ** future product?ontact factory for availability.

detailed description the max4881 max4884/max4893b provide up to +28v overvoltage protection for low-voltage systems. when the input voltage at in exceeds the overvoltage trip level (ovlo), the max4881 max4884/max4893b turn off the low-cost external n-channel fet to prevent damage to the protected components and issue an overvoltage fault flag. the max4881 max4884 feature a built-in current-limited switch that limits the load current to 1.1a (max4881/ max4882), 0.7a (max4883b/max4883c/max4884b/ max4884c), and 0.9a (max4893b). when the load cur- rent is at the current limit for longer than the blanking time, the switch of the max4881/max4882/max4883b/ max4884b/max4893b latches off and does not turn back on until en or cb or in is cycled. a current-limit flag ( flagi ) asserts to indicate a current fault condition. the max4883c/max4884c limit the current to 0.7a indefinite- ly until the thermal protection trips. an overcurrent flag output asserts to indicate a current fault condition after the blanking time has elapsed. in-undervoltage lockout (uvlo) the max4881/max4883 /max4893b have a fixed 4.35v undervoltage lockout level (uvlo) while the max4882/max4884 have a fixed uvlo of 2.55v. gate goes low when v in is below v uvlo , turning off the external n-channel fet. in-overvoltage lockout (ovlo) the max4881/max4883/max4893b have a fixed 5.6v overvoltage threshold (ovlo), while the max4882/ max4884 have a fixed ovlo of 4.5v. gate goes low when v in is higher than v ovlo , turning off the external n-channel fet. fault flag output ( ov ) the ov output signals the host system that there is a fault with the input voltage. ov asserts low in response to either an overvoltage or undervoltage fault. ov stays low for 50ms after gate turns on, before deasserting high. ov is an open-drain active-low output. connect a pullup resistor from ov to the logic i/o voltage of the host system or to any voltage source up to 6v. driving en high disables ov . max4881?ax4884/max4893b overvoltage protection controllers with current limit in tdfn _______________________________________________________________________________________ 7 v in 1.2v v gate v uvlo 0.3v t start 2.4v t 0v-blank 8v t gon v ov 5v figure 1. startup timing diagram v in v gate v ovlo 0.3v t goff 0.4v t ov 4v/5v 7v/8v v ov figure 2. shutdown timing diagram v in i gate v ovlo 80% t ovp 0v figure 3. power-up overvoltage timing diagram v gate 0.3v t dis 2.4v v en figure 4. disable timing diagram
max4881?ax4884/max4893b overcurrent flag output ( flagi ) the max4881 max4884/max4893b have an overcur- rent-fault flag output ( flagi ) to indicate a current fault condition. flagi asserts low to indicate a fault when the current reaches the current limit for longer than the 50ms blanking time. toggle in or cb or en to release flagi latched condition. flagi does not assert if the current- limit fault occurs for less than the blanking time (figure 5). flagi is disabled when en goes high. when cb is low, the switch opens, but flagi is not active. flagi is an open-drain active-low output. connect a pullup resistor from flagi to the logic i/o voltage of the host system or to any voltage source up to 6v. current-limit switch when the forward- or reverse-current-limit threshold is exceeded, t blank timer begins counting. the timer overvoltage protection controllers with current limit in tdfn 8 _______________________________________________________________________________________ load current switch status off current limit on flagi load current switch status t blank t blank t blank t blank current limit on (b) max4883c/max4884c (a) max4881/max4882/max4883b/max4884b/max4893b flagi figure 5. current-limit fault timing load current switch status t blank t blank off on en status (a) flagi pin status load current switch status t blank t blank off on (b) flagi cb status (c) uvlo load current switch status off on flagi t blank t blank status in status status figure 6. latchoff fault blanking (max4881/max4882/ max4883b/max4884b/max4893b
