Description

The eFuse is a 5V protection device with a bidirectional switch that incorporates input slew rate control to reduce input surge current and reverse current detection to prevent discharge to VCC from VOUT. The eFuse protection features include undervoltage lockout, a fixed 2.5A current limit, trimmed fast response overvoltage protection and thermal shutdown. The EN/FAULT line is a tri-state bidirectional interface that can be used to disable the output by pulling the line low through an external open-drain device. If a thermal fault occurs, the voltage on the pin will go to an intermediate voltage indicating a fault and it can be connected to another device to cause simultaneous shutdown. The SAS pin is an ESD protected interface that allows direct external control of the eFuse. Driving the SAS pin high pulls the enable line low causing the eFuse to shut down and enter a low quiescent current state.

The integrated ISOFET latches off when the reverse current is detected. This can be reset only by triggering the undervoltage lockout, by EN/FAULT pin or when voltage on the output pin (V_OUT) falls below the supply pin voltage (V_CC) in the AP91350H.

The AP91350H is available in a standard Green W-QFN3020-12 package and is RoHS compliant.
