TPD1028BS

TPD1028BS TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS IC TPD1028BS Low-Side Switch for Motors, Solenoids, and Lamp Drivers TPD1028BS is a monolithic power IC for low-side switch. The IC has a vertical MOSFET output which can be directly driven from a CMOS or TTL logic circuit (e.g., an MPU). The IC offers intelligent self-protection functions. Features l A monolithic power IC with a new structure combining a control block and a vertical power MOSFET (π-MOS) on a single chip. Built-in Protection circuits against overvoltage, load short circuiting, and thermal shutdown. l Can directly drive a power load from a CMOS or TTL logic. l Weight: 0.36 g (typ.) l Low on-resistance. RDS (ON) = 0.25 (max) (@VIN = 5 V, Tj = 25°C) l Package TO-92(MOD) can be packed in tape. Pin Assignment Note: That because of its MOS structure, this product is sensitive to static electricity. 1 2002-10-24 TPD1028BS Block Diagram Pin Description Pin No. 1 Symbol IN Pin Description Input pin. This pin is connected to a pull-down resistor internally, so that even when input wiring is open-circuited, outputcan never be turned on inadvertently. Output pin. If an inrush current flows (e.g., from a lamp), the current is clamped at 10 A (typ.) by an overcurrent protective circuit. Also, a 150 µs (typ.) mask circuit is included internally, so that if VDS≥12 V (typ.) after this mask time, the current is clamped at 3 A (typ.).
