1 Toshiba Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit TPD38F Motor, Solenoid, Lamp Drivers High-side Power Switch TPD38F The TPD38F 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. SOP8-P-.7A Can directly drive a power load from a microprocessor. Weight:.8g(typ.) Built-in protection against overheating and load short-circuiting. Incorporates a diagnosis function that allows diagnosis output to be read externally at load short-circuiting, opening, or overheating. Up to -(5-VDD)~ -(6-VDD) of counterelectromotive force from an L load can be applied.

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. 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. 6--3
