Part Number MAX4921B
Description Battery Power-Up Logic
Feature MAX4919B/MAX4920B/MAX4921B 19-0614; Rev 0; 8/06 Battery Power-Up Logic with O vervoltage and Overcurrent Protection General Description The MAX4919B/MAX492 0B/MAX4921B overvoltage protection cont rollers protect low-voltage systems aga inst high-voltage faults up to +28V.
An internal 1.
8A (min) pFET with low RON (100mΩ) switches a battery to the loa d and also protects the battery against short-circuit faults.
When a short cir cuit occurs, the current through the in ternal pFET is limited for a blanking p eriod.
If the short condition is presen t after the blanking period, the switch is latched off .
