TPD1033F
TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit
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
A monolithic power IC with a new structure combining a control block (Bi-CMOS) and a vertical power MOS FET (-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 thermal shutdown and load short-circuiting. Weight: 0.08 g (typ.)
Incorporates a diagnosis function that allows diagnosis output to be read externally in the event of load short-circuiting, opening, or overheating. Up to -10 V of counterelectromotive force from an L load can be applied. Low on-resistance Low operating current : RON = 220 m (max) : IDD = 1 mA (typ.), (@VDD = 12 V, VIN = 0 V)
8-pin SOP package for surface mounting can be packed in tape.

Pin Description
Pin No. Symbol Function Input pin. Input is CMOS-compatible, with pull-down resistor connected. Even if the input is open, output will not accidentally turn on. Self-diagnosis detection pin. Goes low when overheating is detected or when output is short-circuited with input on (high). n-channel open drain. Ground pin. Power pin. Output pin. When the load is short-circuited and current in excess of the detection current (8 A typ.) flows to the output pin, the output automatically turns on or off.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
