3-Phase Sensorless Brushless Motor Pre-driver

The TB9061AFNG is an automotive pre-driver IC that incorporates

a sensorless controller for driving a 3-phase full-wave brushless DC

motor.

Feature

・3-phase full-wave sensorless drive

・PWM chopper drive

・Outputs for external P-ch/N-ch MOSFETs drive ( 3-phase 6 outputs)

(Output PWM Dynamic range expansion)

・Suited for both PWM input and DC input control

・Rotating Direction: CW/CCW

・PWM control on lower driver outputs

・Built-in 8-bit AD converter

・Built-in 3-ch comparators to detect induced voltage (Independent 3-phase inputs)

・Built-in overcurrent detector: Detect two values (Current limiter/Overcurrent detection)

・Built-in loss-of-synchronism detection and automatic restart control (Improved Start up)

・5.12-MHz oscillator for reference clock

・Built-in 5-V constant voltage circuit
