Hi Everyone,
I am design a OVP and OCP circuit, and the input voltage is 3.7V~4.2V, max current is 3A.
Here are some requirements:
1. The total impedance of the trace should be less than 0.1ohm.
2. OVP threshold is 6V and OCP threshold is 3A.
3. the OVP and OCP circuit can not draw current from the input rail since I will measure quiescent current, and it is very low, only about several uA.
I have found some OVP and OCP ICs, but the internal power of the ICs was supplied by VIN, so it will draw the current from the input rail.
Do you have any suggestion about it? any suggested IC or circuit.
Thank you.
