MCT8329A Three-Phase BLDC Gate Driver

Texas Instruments MCT8329A Three-Phase BLDC Gate Driver provides a single-chip, code-free sensorless trapezoidal solution for applications requiring high-speed operation or very fast startup time. The device offers three half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The device generates correct gate drive voltages using an internal charge pump and enhances the high-side MOSFETs using a bootstrap circuit. A trickle charge pump is included to support a 100% duty cycle. The gate drive architecture supports peak gate drive currents up to 1A source and 2A sink. The MCT8329A can operate from a single power supply and supports a wide input supply range of 4.5V to 60V.
