TPD1024S TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit TPD1024S Low-Side Power Switch for Motors, Solenoids, and Lamp Drivers TPD1024S 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 self-protection function Features l A monolithic power IC with a new structure combining a control block and a vertical power MOS FET (π-MOS) on a single chip. l Can directly drive a power load from a CMOS logic. l Built-in protection against overvoltage, load short circuiting, and thermal shutdown. l Low on resistance : RDS (ON) = 0.5 Ω(max), (@VIN = 5 V, Tj = 25°C) l 3-pin power-molded package usable for surface mounting. Pin Assignment Weight HSIP3-P-2.30B HSOP3-P-2.30A Note: : 0.36 g (typ.) : 0.28 g (typ.) That because of its MOS structure, this product is sensitive to static electricity. 1 2002-10-24 TPD1024S Block Diagram Pin Description Pin No. Symbol Function 1 IN Input pin. Input is CMOS-compatible, with pull-down resistor connected. Even if the input is open, output will not accidentally turn on. 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 GND Ground pin.
