TPIC43T01 - THREE-PHASE BRUSHLESS MOTOR RPM CONTROLLERS

General Description

The TPIC43T01/02 is a monolithic motor control integrated circuit designed to provide RPM control to a 3-phase brushless dc motor.

The device provides two analog sensor input ports which include a speed sensor interface and a Hall effect position interface.

The speed feedback interface consists of an FG amplifier to receive an external sinusoidal signal from a variable reluctance pickup and convert it to a digital speed signal for the control circuit.
