TPD4123K Description

Short technical summary and product information.

The TPD4123K from Toshiba is a high-voltage monolithic silicon power IC designed for driving DC brushless motors. Fabricated using a high-voltage SOI process, it integrates a 3-phase bridge output using IGBTs, along with essential protective functions including over-current, under-voltage, and thermal shutdown.

 

This device utilizes a three-shunt resistor circuit for current sensing, offering optimal performance for current measurement. It includes built-in bootstrap diodes and a bootstrap circuit for a simple high-side supply. The TPD4123K allows for a minimum dead time setting of 1.4 μs, making it suitable for sine-wave drive applications. It also features a built-in regulator providing a typical 7V output.

 

The TPD4123K is housed in a 26-pin DIP package. Its design separates the high-voltage power side from the low-voltage signal side, simplifying control by logic inputs from a MPU or motor controller. This IC is sensitive to electrostatic discharge and requires appropriate handling precautions.
