Overview

The DRV8353HMRTAT is a highly integrated 100V triple gate driver designed for three-phase brushless DC (BLDC) motor applications. It features a smart gate drive architecture that eliminates the need for external gate resistors by providing adjustable slew rate control and protection against dV/dt parasitic turn-on. The device includes three integrated current shunt amplifiers with adjustable gain to simplify motor current sensing and feedback loops.

Why Choose This Part

This driver simplifies system design by integrating three current shunt amplifiers and a high-side charge pump that supports 100% PWM duty cycle. The hardware (HW) interface version allows for configuration via resistor settings, removing the need for an SPI bus while providing comprehensive protection including UVLO, GDUV, and VDS overcurrent monitoring.

Applications

Industrial Robotics
High-voltage motor drive for robotic arms and automated guided vehicles requiring precise current sensing.
E-Bikes and E-Scooters
Efficient 48V or 72V BLDC motor control with 100% duty cycle support for maximum speed range.
Cordless Power Tools
Compact motor drive using integrated amplifiers and hardware-based fault protection to reduce PCB footprint.
Drones and UAVs
Electronic speed controllers (ESCs) benefiting from the integrated charge pump and thermal protection.
