Abstract
A power MOSFET drain-source on resistance (Rdson) compensation device comprises circuitry configured to receive an input signal proportional to a voltage drop across a power MOSFET, a temperature dependent information and a gate-source voltage dependent information. The circuitry includes control logic and a first linear discrete voltage divider, wherein the first linear discrete voltage divider is configured to output a compensated voltage based on an at least one compensating control signal from the control logic that is based on at least one of the temperature dependent information or gate-source voltage dependent information.
