TPD4104AK
TOSHIBA Intelligent Power Device High Voltage Monolithic Silicon Power IC
TPD4104AK
The TPD4104AK is a DC brush less motor driver using high
voltage PWM control. It is fabricated by high voltage SOI process.
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 TPD4104AK.

Bootstrap circuit gives simple high side power supply.
Bootstrap diodes are built in.
A dead time can be set as a minimum of 1.4 µs, 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: 23-pin HZIP.
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.
