The capacitor return should be connected directly to the GND pin. 4 SAS SAS Disable, When this pin is pulled high to a voltage greater than 2.1V, the eFuse is turned off.
5 EN/FAULT
The EN/FAULT pin is a tri−state, bidirectional interface. It ca n be used to enable or disable the output of the device by pulling it to ground using an open drain device. If a thermal fault occurs, the voltage on this pin will go to an intermediate state to signal a monitoring circuit that the device is in thermal shutdown. It can also be connected to another device in this family to cause a simultaneous shutdown during thermal events. 6, 7, 8 NC Do not connect on PCB, internally connected for production purpose 9, 10, 11 VOUT Output: eFuse controlled output; a 20µF capacitor is needed for over voltage protection stability. The capacitor return should be connected directly to the GND pin.

Typical data is measured at T A = +25C, VCC = 5V. The maximum and minimum parameters values over operating temperature range are not tested in production, they are guaranteed by design, characterization and process control. 7. The slew rate control is held in reset until the input voltage is greater than the UVLO rising threshold and Ena ble = High. The slew rate control is reset when input voltage drops below UVLO falling threshold, Enable changes from High to Mid or Low, SA = Hig h or reverse current detection. 8. Reverse current detection will latch off the Isofet switch ; In AP91352, this condition can be reset by under voltage lock out, by EN/FAULT and SAS pin, or when VOUT falls below the supply pin voltage (VCC) by 100mV typical at TA = +25C, VCC = 5V.
