TPD4123AK TOSHIBA Intelligent Power Device High Voltage Monolithic Silicon Power IC www.DataSheet4U.com TPD4123AK The TPD4123AK 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 l

TPD4123AK Features

* High voltage power side and low voltage signal side terminal are separated. It is the best for current sensing in three shunt resistance. Bootstrap circuit gives simple high-side supply. Bootstrap dio
