Overvoltage Protection Controllers with

Current Limit in TDFN

General Description

Features

The MAX4881–MAX4884/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.

ꢀ Undervoltage Lockout

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.

ꢀ Thermal Shutdown Protection

ꢀ Tiny 10-Pin TDFN Package

Pin Configuration

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.

*EP

The MAX4881–MAX4884/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.
