A3944 Overview
The A3944 is a programmable six-channel low-side MOSFET pre-driver suitable for use in automotive applications. Each channel is controllable by a bination of parallel and serial inputs and provides sufficient gate drive current to allow PWM control up to 20 kHz, depending on the MOSFET gate charge. Each channel provides independent fault diagnostics for shortto-ground and open load when in the off-state, and...
