Overview

The TC78B009FTG is a three-phase brushless DC (BLDC) motor controller designed to drive external N-channel MOSFETs for high-power applications. It operates from a supply voltage of 5.5V to 27V and features a sensorless drive architecture that eliminates the need for Hall effect sensors in the motor assembly.

Why Choose This Part

This controller minimizes system cost and complexity by using sensorless commutation logic and integrating a pre-driver capable of 240mA output to toggle external gates. It supports I2C for flexible parameter tuning and features a very low standby current of 10uA to extend battery life in portable designs.

Applications

High-Speed Cooling Fans
Ideal for server and industrial cooling systems requiring efficient sensorless commutation at high RPMs.
Portable Vacuum Motors
Suitable for cordless appliances where compact 36-pin WQFN packaging and low standby current are critical.
Industrial Pumps
Provides reliable motor control for fluid delivery systems using I2C or PWM interfaces for speed management.

Getting Started

To begin development, interface the TC78B009FTG with an MCU via the I2C bus to configure internal registers for startup timing and lead angle control. Engineers should select external N-channel MOSFETs based on the target motor voltage and current, ensuring the pre-driver current is sufficient for the chosen gate charge.
