TPD1045F is an integrated circuit used for driving motors, solenoids, and lamps. It has protection features and low on-resistance.
The Toshiba TPD1045F is a low‑side power MOSFET switch designed for motor, solenoid and lamp drive applications. It integrates a vertical power MOSFET and control circuitry on a single chip, allowing direct drive from CMOS or TTL logic and providing built‑in protection functions.
The document provides a block diagram, pin description, absolute maximum ratings, electrical and thermal characteristics, and package dimensions. It also includes safety notes and handling precautions for the MOSFET structure. This manual is written in Japanese.
| On‑resistance (RDS(on)) | 100 mΩ (max) at V_RN=5V, I_D=2A, T=25°C |
|---|---|
| Drain‑Source Voltage (V_DSS) | 50 V |
| Input Voltage Range (V_N) | -0.3 to 7 V |
| Operating Temperature Range | -40 °C to 125 °C |
| Current‑limit detection | 10 A (standard) |
The device is rated for a maximum drain‑source voltage of 50 V.
The on‑resistance is specified as 100 mΩ maximum at V_RN = 5 V, I_D = 2 A, and 25 °C.
It includes over‑voltage, over‑temperature, and over‑current protection circuits.
Because the device uses a MOS structure, it must be protected from electrostatic discharge during handling.
