Abstract
An over-current protection sensor circuit is disclosed. The circuit includes: a reference current source, configured to source a reference current; a reference MOS transistor, configured to receive the reference current and a gate voltage, and to generate a reference drain voltage based at least in part on the reference current and the gate voltage; an operational amplifier, configured to receive a reference voltage and to generate the gate voltage based on a difference between the reference voltage and the reference drain voltage; an output MOS transistor, configured to receive an input current and the gate voltage, and to generate an output drain voltage based at least in part on the input current and the gate voltage; and a comparator, configured to generate an over-current signal based on a difference between the reference drain voltage and the output drain voltage.
