TPD1033F

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

The TPD1033F 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

z 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

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

z Can directly drive a power load from a microprocessor.

z Built-in protection against thermal shutdown and load

Weight: 0.08 g (typ.)

short-circuiting.

z Incorporates a diagnosis function that allows diagnosis output to be read externally in the event of load

short-circuiting, opening, or overheating.

z Up to -10 V of counterelectromotive force from an L load can be applied.

z Low on-resistance

: RON = 220 mΩ (max)

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

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