TPD4135K is a high-voltage SOI process DC brushless motor driver that supports 3 shunt resistance current detection. It integrates level-shifted high-side driver, low-side driver, overcurrent protection circuit, over-temperature protection circuit, under-voltage protection circuit, output IGBT and FRD, which can directly drive variable-speed DC brushless motor by microcontroller control signal.
The TPD4135K is a high‑voltage, PWM‑controlled brushless motor driver IC with three‑shunt current detection, built‑in protection circuits, and a bootstrap high‑side driver. It is supplied in a 26‑pin DIP package and is intended for use with DC brushless motors.
Key features include separate high‑voltage and control pins, built‑in bootstrap diodes, minimal dead‑time of 1.4 µs, and integrated over‑current, over‑temperature, and undervoltage protection. The datasheet lists absolute maximum ratings, pin functions, and typical application circuits. This manual is written in Japanese.
