We are now introducing the DRV8302 three-phase brushless DC motor gate driver to our customers. This product is brand-new, genuine, and available in stock. Please feel free to contact us for more information!

DRV8302 Product Overview

The DRV8302 is a high-performance gate driver IC developed by Texas Instruments (TI) specifically for driving three-phase brushless DC motors (BLDC) and permanent magnet synchronous motors (PMSM). This device integrates three half-bridge drivers capable of driving six N-channel power MOSFETs. It features a built-in bootstrap gate driver architecture and a trickle-charge circuit, supporting 100% duty cycle operation.

The DRV8302 features a hardware control interface that allows flexible configuration of key parameters—such as dead-time, overcurrent protection threshold, PWM mode, and amplifier gain—via external resistors, greatly simplifying system design. It is an ideal drive solution for applications in industrial automation, power tools, robotics, and drones.

DRV8302 Key Technical Features

1. Wide Voltage Range and Robust Drive Capabilities

Supports single-supply voltages from 8 V to 60 V, covering mainstream low- to medium-voltage motor drive applications. Gate drive capability of 1.7A sink current and 2.3A source current ensures rapid switching of power MOSFETs, effectively reducing switching losses.

2. 100% Duty Cycle Support

Utilizes a bootstrap gate driver architecture combined with a trickle-charge circuit to ensure that the high-side MOSFET receives sufficient gate drive voltage even under 100% duty cycle conditions.

3. Integrated Current Sensing

Two built-in shunt amplifiers support bidirectional current sensing, with externally adjustable gain and offset, providing precise current feedback for Field-Oriented Control (FOC) and six-step commutation.

4. Integrated Buck Converter

An on-chip buck converter with adjustable output voltage and switching frequency is integrated, capable of delivering up to 1.5A of current. It can directly power the MCU or other system circuits, reducing the number of external components.

5. Comprehensive System Protection

Integrated programmable dead-time control prevents through-short circuits, while VDS sensing provides overcurrent protection. Additionally, multiple protection mechanisms—including under-voltage, over-voltage, and over-temperature protection—ensure safe and reliable system operation.

Typical Applications

The DRV8302 is widely used in various three-phase motor drive applications:

Industrial Automation: Servo drives, robots, industrial motor control

Power Tools: Cordless drills, electric saws, angle grinders

Personal Mobility: Electric bicycles, scooters

Home Appliances and Medical Devices: CPAP machines, water pumps, fans

Consumer Electronics and Toys: Drones, RC models

Automotive Electronics: Auxiliary motors such as water pumps, fuel pumps, and cooling fans
