TPIC43T01 

Three-phase brushless motor RPM controller

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.   characteristic   High-precision phase-locked loop motor - speed loop compensation filter control algorithm with embedded DSP For the user's PLL loop gain, adjust the EEPROM register and DSP (rod/zero) filter factor Crystal oscillator with EEPROM adjustable divider phase-locked loop for universal time Standalone operation does not require a processor for a host Speed Lock Detection/Reporting (± 5% window) Synchronous Rectification Enable (TPIC43T01) Disable (TPIC43T02) Faulty motor timer/shutdown High side current limit The high side is cut off The input/decoding of the differential Hall effect position sensor provides commutation control Input speed of differential variable reluctance sensor The gate-driven six external N-channel power FETs are in a three-and-a-half-H configuration The charging pump develops a high side gate drive voltage 5 V Regulator - Designed for an external current of 10 mA 8 to 28 V supply voltage Small form factor surface mount package
