Overview
MAX4919B/MAX4920B/MAX4921B 19-0614; Rev 0; 8/06 Battery Power-Up Logic with Overvoltage and Overcurrent Protection General Description The MAX4919B/MAX4920B/MAX4921B overvoltage protection controllers protect low-voltage systems against high-voltage faults up to +28V.
An internal 1.
8A (min) pFET with low RON (100mΩ) switches a battery to the load and also protects the battery against short-circuit faults.
When a short circuit occurs, the current through the internal pFET is limited for a blanking period.
If the short condition is present after the blanking period, the switch is latched off and remains off until one of the input signals (IN, HP_PWR, PWR_ON) is cycled.
The pFET is turned on...
