High Voltage Monolithic Silicon Power IC

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.

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 1.4μs, and it is the best for a Sine-wave from drive.

• 3-phase bridge output using IGBTs.

• FRDs are built in.

• Included under voltage protection and thermal shutdown.

• The regulator of 7V (typ.) is built in.

• 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.
