| TPD1038F Toshiba Intelligent Power Device Silicon Monolithic Power MOS Integrated circuit TPD1038F Motor, Solenoid, Lamp Drivers High Side Power Switch 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 (eg, 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 against overheating and load short circuiting. 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 can be packed in tape.
