Description
The A3942 is a highly-integrated gate driver IC that can drive
up to four N-Channel MOSFETs in a high-side configuration.
The device is designed to withstand the harsh environmental
conditions and high reliability standards of automotive
applications.
Serial Peripheral Interface (SPI) compatibility makes the device
easily integrated into existing applications. The MOSFETs in
such applications are typically used to drive gasoline or diesel
engine management actuators, transmission actuators, body
control actuators and other general-purpose automotive or
industrial loads. In particular, the A3942 is suited for driving
glow plugs, valves, solenoids, and other inductive loads in
engine management and transmission systems.
The device is available in a 38-lead thin (1.20 mm maximum
overall height) TSSOP package with six pins that are fused
internally to provide enhanced thermal dissipation (package
LG). It is lead (Pb) free with 100% matte tin leadframe
plating.
