High-side Power Switch for Motors, Solenoids, and Lamp Drivers

The TPD1034F is a monolithic power IC for high-side switches. The IC has a vertical MOS FET output which can be directly driven from a CMOS or TTL logic circuit (e.g., an MPU). The device offers intelligent self-protection and diagnostic functions.

Features

A monolithic power IC with a new structure combining a control block (Bi-CMOS) and a vertical power MOS FET (π-MOS) on a single chip.

One side of the load can be grounded to a high-side switch.

Can directly drive a power load from a microprocessor.

Built-in protection against thermal shutdown and load short-circuiting.

Incorporates a diagnosis function that allows diagnosis output to be read externally at load short-circuiting, opening, or overtemperature

Up to −10 V of counter electromotive force from an L load can be applied.

Low on-resistance : RON = 80 mΩ(max)

Low operating current : IDD= 1 mA (typ.), (@VDD= 12 V, VIN= 0 V)

8-pin SOP package for surface mounting can be packed in tape.
