Overvoltage-Protection Controller with  
Internal Disconnect Switch  
General Description  
Features  
The MAX4880 is an overvoltage-protection controller  
with an internal current-limited switch that can be con-  
figured as a low-cost battery charger. When the input  
voltage exceeds the overvoltage trip level (5.7V), or  
drops below the undervoltage-lockout level (4.2V), the  
MAX4880 turns off the external n-channel MOSFET and  
asserts an undervoltage/overvoltage flag indicator  
(FLAGV) low to notify the processor.  
♦ Overvoltage Protection Up to 28V  
♦ Preset 5.6V Overvoltage Trip Level  
♦ Internal 525mA Current-Limited Switch  
♦ ±±.2ꢀ Accurate ꢁatterꢂ ꢃisconnect ꢄ(.2Vꢅ  
♦ ꢃrives Low-Cost n-Channel MOSFET  
♦ Internal 50ms Startup ꢃelaꢂ  
The MAX4880 internal current-limited switch limits the  
charge current flowing to the battery to 525mA. The  
switch opens when the battery voltage reaches its full-  
charged state (4.2V), and a flag (BAT_OK) asserts to  
notify the processor. The MAX4880 includes a switch-  
control input (CB) to turn off the internal current-limited  
switch, regardless of the battery voltage.  
♦ Overvoltage/Undervoltage-Fault FLAGV Indicator  
♦ ꢁatterꢂ-Voltage-Trip BAT_OK Indicator  
♦ Undervoltage Lockout  
♦ Thermal Shutdown Protection  
♦ Tinꢂ ±0-Pin TꢃFN Package  
The MAX4880 also features a built-in startup delay that  
allows the adapter voltage to settle down before turning  
on the MOSFET. Other features include 15kV ESD pro-  
tection for the input and a shutdown function (EN) to  
turn off the external n-channel MOSFET.  
Ordering Information  
The MAX4880 is available in a space-saving 10-pin  
TDFN package and is specified for operation over the  
extended -40°C to +85°C temperature range.
