TC78B027FTG
Overview
The TC78B027FTG is a three-phase brushless DC (BLDC) motor controller designed to drive external N-channel MOSFETs. It features a unique 1-Hall sine-wave PWM drive algorithm that provides efficient motor rotation with reduced vibration and acoustic noise compared to traditional square-wave drivers.
Why Choose This Part
This controller integrates a closed-loop speed control function that maintains constant RPM despite varying load or supply voltage. It simplifies system design by using a single Hall sensor input to achieve sine-wave commutation, reducing the component count and PCB footprint in the motor assembly.

Key Specifications
Getting Started
Engineers can configure the TC78B027FTG via its serial interface (I2C/SPI) to tune the speed curve and gate drive current for specific external MOSFETs. Evaluation involves connecting a 5V to 16V supply to VM and monitoring the FG output for real-time RPM feedback during development.
