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. When the motor speed is outside a
鹵
5% window of the reference signal, an out-of-lock condition is
declared. The Hall ffect sensor input section receives low-level differential voltages from external naked Hall
elements and converts them to digital position reference signals for the control circuit for commutation control.
The core of the control circuit implements a digital signal processing algorithm consisting of a digital integrator
and filter with user adjustable parameters to optimize the closed loop performance of the control system. The
device contains an internal EEPROM to set integrator gain and digital filter coefficients. In addition, Texas
Instruments provides a PC based Windows鈩?compatible software package to input the motor and system
characteristics and convert them to control parameters for the TPIC43T01/02. The software generates a JEDEC
compatible file to program the device through a third party device programmer.
