A89506KESSR-J Image

The A89506KESSR-J from Allegro Microsystems is an Automotive Qualified Full-Bridge Gate Driver IC that is designed to provide pulse width modulation (PWM) control for DC motors and actuators in conventional, hybrid, and electric vehicles. This gate driver has an input voltage from 5.5-50 V. It is capable of providing gate drive for all N-Channel external MOSFET bridge circuits. This gate driver consists of a PHASE/ENABLE/MODE control logic to control the speed and direction of a DC motor with externally applied PWM control signals. It is based on a solid-state design that incorporates brushed DC motors to improve reliability and battery life. This gate driver IC is designed to minimize the external circuitry by replacing mechanical relays with solid-state drivers, thereby improving reliability. It senses and provides current information feedback using an analog logic level output.

This AEC-Q100 qualified gate driver has MOSFET VDS protection, internal UVLO, crossover-current protection, and an adjustable current limit to protect against short-circuit-related damages. It is available in a surface-mount package that measures 4 x 4 mm and is ideal for EV charger locks, electronic parking brakes, folding mirrors, and window and door actuator applications.
