Quad High-Side Gate Driver

for Automotive Applications

Features and Benefits

▪ Drives four N-channel high-side MOSFETS

▪ Charge pump for 100% duty cycle operation

▪ Serial and discrete inputs

▪ SPI port for control and fault diagnostics

▪ 4.5 to 60 V input voltage range

▪ Sleep function for minimum power drain

▪ Thin profile 38-lead TSSOP with internally fused leads for

enhanced thermal dissipation

▪ Lead (Pb) free

▪ Device protection features:

▫ Short-to-ground detection (latched)

▫ Short-to-battery protection (latched)

▫ Open load detection (latched)

▫ V_DDundervoltage lockout

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.

SerialPeripheralInterface(SPI)compatibilitymakesthedevice

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.

▫ V_CPundervoltage lockout

▫ Thermal monitor

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.

Package: 38 pin TSSOP (suffix LG)
