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.

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.

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.
