Overvoltage Protection Controllers with  
Status FLAG  
General Description  
Features  
The MAX4838–MAX4842 are overvoltage protection ICs  
that protect low-voltage systems against voltages of up  
to 28V. If the input voltage exceeds the overvoltage trip  
level, the MAX4838–MAX4842 turn off the low-cost  
external n-channel FET(s) to prevent damage to the  
protected components. An internal charge pump elimi-  
nates the need for external capacitors and drives the  
FET gate for a simple, robust solution.  
♦ Overvoltage Protection Up to 28V  
♦ Preset 7.4V, 5.8V, or 4.7V Overvoltage Trip Level  
♦ Drive Low-Cost NMOS FET  
♦ Internal 50ms Startup Delay  
♦ Internal Charge Pump  
♦ Undervoltage Lockout  
The MAX4838/MAX4839 have a 7.4V overvoltage  
threshold, and the MAX4840/MAX4841 have a 5.8V  
overvoltage threshold. The MAX4842 has a 4.7V over-  
voltage threshold. The MAX4838–MAX4841 have an  
undervoltage lockout (UVLO) threshold of 3.25V while  
the MAX4842 has a UVLO of 3.0V. In addition to the  
single FET configuration, the devices can be config-  
ured with back-to-back external FETs to prevent cur-  
rents from being back-driven into the adapter.  
♦ 15kV ESD-Protected Input  
♦ Voltage Fault FLAG Indicator  
♦ 6-Pin SC70 Package  
Ordering Information  
On power-up, the device waits for 50ms before driving  
GATE high. FLAG is held low for an additional 50ms  
after GATE goes high before deasserting. The  
MAX4838/MAX4840/MAX4842 have an open-drain  
FLAG output, and the MAX4839/MAX4841 have a push-  
pull FLAG output. The FLAG output asserts immediately  
to an overvoltage fault.

Additional features include a 15kV ESD-protected input  
(when bypassed with a 1µF capacitor) and a shutdown  
pin (EN) to turn off the device (MAX4838/MAX4840/  
MAX4842).  
All devices are offered in a small 6-pin SC70 package  
and are specified for operation from -40°C to +85°C.
