TPIC43T02

illustrate

The TPIC43T01/02 is a monolithic motor control integrated circuit designed to provide speed control 3-phase brushless DC motor. The device provides two analog sensor input ports, including a speed sensor interface and a Hall effect position interface. The speed feedback interface includes an FG amplifier to receive a sinusoidal signal from an external variable reluctance pickup and convert it into a digital speed signal for the control circuit. When the speed of the motor ± 5% of the reference signal window, a complete lock condition declaration. The input portion of the Hall sensor ffect receives a low-level differential voltage from an external bare Hall element and converts it into a reference signal for a conversion control circuit for digital position control.
