TPD1024AS TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit TPD1024AS Low-side Power Switch for Motors, Solenoids, and Lamp Drivers The TPD1024AS is a monolithic power IC for low-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 is equipped with an intelligent self-protection function. Features z A monolithic power IC with a new structure combining a control block and a vertical power MOS FET (π-MOS) on a single chip z Can directly drive a power load from a CMOS logic. z Built-in protection against overvoltage, load short-circuiting, and thermal shutdown z Low on-resistance : RDS (ON) = 0.5 Ω (max) (@VIN = 5 V, Tj = 25°C) z Package : TPS that can be packed in tape. Weight: 0.54g (typ.) Pin Assignment Note: Due to its MOS structure, this product is sensitive to static electricity. Marking TPD1024AS Part No. (or abbreviation code) Lot No. A line indicates lead (Pb)-free package or lead (Pb)-free finish. 1 2006-10-31 TPD1024AS Block Diagram Pin Description Pin No. Symbol Function 1 GND Ground pin. 2 OUT Output pin. When current in excess of the typical current (3.5 A (typ.)) flows to the output pin, the current limiter operates to protect the IC. 3 IN Input pin. Input is CMOS-compatible, with pull-down resistor connected. Even if the input is open, output will not accidentally turn on.
