Toshiba Intelligent Power Device
TPD1038F
Silicon Monolithic Power MOS Integrated Circuit
Motor, Solenoid, Lamp Drivers High-side Power Switch
The TPD1038F 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 structure combining a control block (Bi-CMOS) and a vertical power MOS FET 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 short-circuiting. against overheating and load SOP8-P-1.27A Weight0.08g(typ.)
* * * * * * *
Incorporates a diagnosis function that allows diagnosis output to be read externally at load short-circuiting, opening, or overheating. Up to -(50-VDD) -(60-VDD) of counterelectromotive force from an L load can be applied. Low on-resistance : RDS(ON)=120m(max) ( @ VDD = 12 VTa = 25Io = 2 A) 8-pin SOP package for surface mounting that can be packed in tape

Pin Description
Pin No. 1 2 3 4 5,6,7,8 Symbol OUT GND DIAG IN VDD Function Output pin. When the load is short-circuited and current in excess of the detection current (3A min) flows to the output pin, the output automatically turns on or off. Ground pin. Self-diagnosis detection pin.Goes low when overheating is detected or when output is short circuit with input on (high). N-channel open drain. Input pin. Input is CMOS compatible, with pull down resistor connected. Even if the input is open, output will not accidentally turn on. Power pin.

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).
