TPD1052F is a power switch chip for motors, solenoids and lamps. The chip uses a BiCMOS control and DMOS power MOSFET structure, and has the characteristics of low RDS(ON) and low IDD. It can be directly driven from the microcontroller end to the load, and has built-in over-temperature and over-current protection functions.
The TPD1052F is a DMOS8 high‑side power switch designed for motor, solenoid and lamp drive applications. It integrates a BiCMOS control block and a power MOSFET on a single chip, providing built‑in protection and diagnostic functions.
The document includes a block diagram, pin definitions, electrical characteristics, maximum ratings, thermal data, application circuits and package dimensions, allowing designers to evaluate and implement the device in their systems. This manual is written in Japanese.
