TPD4144K
Intelligent power device 500V (High voltage PWM DC brushless motor driver)
TPD4144K
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. The regulator of 7 V (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.
Weight: 3.8 g (typ.)
