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

The TPD1018F is a monolithic power IC for high-side switches. The IC has a vertical MOS FET output that can be directly driven from a CMOS or TTL logic circuit (e.g., an MPU). The device is equipped with 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 load can be grounded to a high-side switch

Can directly drive a power load from a microprocessor.

Built-in protection against overvoltage, thermal shutdown, and load short-circuiting

Incorporates a diagnosis function that allows diagnosis output to be read externally in the event of loadshort-circuiting, overvoltage, or overheating.

Low on-resistance : RDS (ON)= 0.8Ω(max)

Low operating current : IDD= 120μA (typ.) (@VDD= 13.2V, VIN= 0V)

10-pin SSOP package for surface mounting
