Overvoltage Protectors with  
External pFET  
3–MAX4926  
General Description  
Features  
The MAX4923–MAX4926 overvoltage protection  
(OVP) controllers protect low-voltage systems against  
high-voltage faults of up to +28V with an appropriate  
external pFET. When the input voltage exceeds the over-  
voltage lockout (OVLO) threshold, or falls below the  
undervoltage lockout (UVLO) threshold, these devices  
turn off the pFET to prevent damage to protected compo-  
nents and issue a flag to notify the processor of a fault  
condition.  
o Overvoltage Protection Up to +28V  
o Preset 7.18V, 6.16V, 5.65V, and 4.46V Typical  
Overvoltage Trip Levels  
o Preset 2.44V Typical Undervoltage Trip Level

Trip Levels  
o Low 13µꢁ (typ) Sꢂpply Cꢂrrent  
o Drives External pFET  
The typical overvoltage trip level is set to 7.18V  
(MAX4923), 6.16V (MAX4924), 5.65V (MAX4925), and  
4.46V (MAX4926). The undervoltage trip level is set to  
2.44V (typ) for all devices.  
o 20ms ꢁdapter Deboꢂnce Time  
o Faꢂlt Flag Indicator  
The input (IN) is ESD protected to 15kV ꢀHM when  
bypassed to ground with a 1µF ceramic capacitor. All  
devices are offered in a small, 6-pin (1.5mm x 1.0mm)  
µDFN package and are specified over the extended  
-40°C to +85°C temperature range.
