TPD1032F Toshiba Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit TPD1032F 2-IN-1 Low-Side Power Switch for Motor, Solenoid and Lamp Drive The TPD1032F is a 2-IN-1 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 is equipped with intelligent self-protection functions. Features • Two built-in power IC chips with a new structure combining a control block and a vertical power MOSFET (L2-π-MOS) on each chip. • Can directly drive a power load from a CMOS or TTL logic. • Built-in protection circuits against overvoltage (active clamp), overtemperature (thermal shutdown), and overcurrent (current limiter). • Low Drain-Source ON-resistance: RDS (ON) = 0.4 Ω (max) (@VIN = 5 V, ID = 1 A, Tch = 25°C) • Low Leakage Current: IDSS = 10 μA (max) (@VIN = 0 V, VDS = 20 V, Tch = 25°C) Weight: 0.08 g (typ.) • Low Input Current: IIN = 300 μA (max) (@VIN = 5 V, Tch = -40～110°C) • 8-pin SOP package for surface with embossed-tape packing.

Source pin 2 Input pin 2 This pin is connected to a pull-down resistor internally, so that even when input wiring is open-circuited, output can never be turned on inadvertently. Drain pin 2 Drain current is limited (by current limiter) if it exceeds 3 A (min) in order to protect the IC. Drain pin 1 Drain current is limited (by current limiter) if it exceeds 3 A (min) in order to protect the IC. 2 2006-10-31 TPD1032F Timing Chart Input Signal Overcurrent Protection Overtemperature Protection Output Current Current limiting (limiter) Overtemperature protection (Note2) Note2: The overheating detector circuits feature hysteresis. After overheating is detected, normal operation is restored only when the channel temperature falls by the hysteresis amount (5°C typ.) in relation to the overheating detection temperature.
