TOSHIBA Intelligent Power Device

High Voltage Monolithic Silicon Power IC

TPD4144K

The TPD4144K 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 over-current circuit and 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 TPD4144K.

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 diodes are built in.

• A dead time can be set as a minimum of 1.4 μs, and it is suitable for a Sine-wave from drive.

• 3-phase bridge output using IGBTs.

• FRDs are built in.

• Included over-current and under-voltage protection, and thermal shutdown.

• Package: 26-pin DIP.

This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product, ensure that

the environment is protected against electrostatic discharge.
