High voltage

3-Phase Full-Wave PWM Brushless Motor Driver

Features

• A Controller and a high-voltage driver are integrated in a single package.

Sine-wave PWM drive or wide-angle commutation drive is selectable.

• IGBTs are arranged in three-phase bridge unit.

• Built-in oscillator circuit (carrier frequency = fosc/252 (Hz))

• Bootstrap circuitry: Built-in bootstrap diode

• Built-in overcurrent protection, thermal shutdown, undervoltage lockout, and motor-lock detection.

• Internal voltage regulator circuit (VREG = 5 V (typ.), 30 mA (max), Vrefout = 5 V (typ.), 35 mA (max))

• Operating power supply voltage range: VCC = 13.5 to 16.5 V

• Motor power supply operating voltage range: VBB = 50 to 450 V
