TPD4144AK
The TPD4144AK is a DC brush less motor driver using high voltage
PWM control. It is fabricated by high voltage SOI process. It is
three-shunt resistor circuit for current sensing. It contains level
shift high-side driver, low-side driver, IGBT outputs, FRDs and
protective functions for under voltage protection circuits and
thermal shutdown circuit. It is easy to control a DC brush less
motor by just putting logic inputs from a MPU or motor controller to
the TPD4144AK.
