Abstract
Aspects of the disclosure provide for a circuit. In at least some examples, the circuit includes a logic circuit, a first comparator, a second comparator, and an AND logic circuit. The logic circuit has an output and the first comparator has a first input coupled to an input voltage (VIN) pin, a second input configured to receive a Vin under voltage lockout (VINUVLO) threshold value, and an output. The second comparator has a first input coupled to a power middle (PMID) pin, a second input coupled to a battery pin, and an output and the AND logic circuit has a first input coupled to the output of the logic circuit, a second input coupled to the output of the first comparator, a third input coupled to the output of the second comparator, and an output coupled to an input of a field-effect transistor (FET) control circuit.
