The Fault function asserted during overcurrent, overtemperature, or reverse-voltage conditions.
I'm confuse the overcurrent condition,
1: If I set the current limit is 75mA and my load is 200mA, does the Fault function enable??
2: what is the overcurrent condition for the fault function?
3: for the auto-retry function, please share the R/C time equation between Fault and En pin.
Hi Gordon,
E is Vin. caculate t as Vc(t) arrives Enable threshold 1.1V.

If I use the auto-retry function circuit and set the current limit is 75mA and my load is a super-cap.
And then the Fault function always disable the chip and cuper-cap always don't charge.
So, I can't use the circuit for charging function???
Does it make sense??
Hi Gordon,
1. For current limit of 75mA, please refer to the following table on page 20 of datasheet:
2. The fault will assert as current limit not only for short circuit.
3. With auto re-retry function, still can charge the super-cap. We call the current average current although has a period off time.
I know your concern. For details, you can refer to the following information on page 22 of datasheet.
