TPD1024AS

TPD1024AS TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit TPD1024AS Low-Side Power Switch for Motors, Solenoids, and Lamp Drivers 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 offers intelligent selfprotection function. Features A monolithic power IC with a new structure combining a control block and a vertical power MOS FET(π-MOS) on a single chip. Can directly drive a power load from a CMOS logic. Built-in protection against overvoltage, load short circuiting, and thermal shutdown. Low on resistance : RDS (ON) = 0.5 Ω (max) (@VIN = 5 V, Tj = 25°C) Package : TPS Can be packed in tape. Weight: 0.54g (typ.) Pin Assignment Note: That because of its MOS structure, this product is sensitive to static electricity. 1 2002-10-24 TPD1024AS Block Diagram Pin Description Pin No. 1 2 Symbol GND OUT Ground pin. 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. Input pin. Input is CMOS-compatible, with pull-down resistor connected. Even if the input is open, output will not accidentally turn on.
