Configurable high/low side driver using a low-side fet pre-driver

摘要

A high-side driver circuit for driving a load, including a low-side driver IC (12) having a drive output (16) and a feedback input (18), a first transistor (Q1) coupled to the drive output (12), and a second transistor (M1) coupled between a power source and the load. The second transistor (M1) is configured to enter an "OFF" state when the first transistor (Q1) is driven into an "OFF" state by the drive output, and to enter an "ON" state when the first transistor (Q1) is driven into an "ON" state by the drive output.
