CDMOS Linear Integrated Circuit Silicon Monolithic

TC78B011FTG

Sensorless Sine-wave PWM predriver for 3-phase brushless motor

1. Outline

The TC78B011FTG is a 3-phase PWM chopper predriver

for sensorless brushless motor. Motor speed can be controlled

by selecting among the PWM duty cycle, analog voltage, and I²C.

Non-volatile memory (NVM) is implemented and it can set

according to the motors and directions for use. It also realizes closed

loop speed control function without an external microcontroller.

TC78B011FTG is used with six external MOSFETs inverter to drive

sensorless brushless motors of which output range is wide.

P-WQFN36-0505-0.50-001

Weight: 0.06 g (typ.)

2. Applications

Fan, Pump, Portable Vacuum motors
