TPD1044F Toshiba Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit TPD1044F Low-Side Switch for Motor, Solenoid and Lamp Drive The TPD1044F is a 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 • A monolithic power IC with a new structure combining a control block and a vertical power MOSFET (L2-π-MOSⅤ) on single chip. • Can directly drive a power load from a CMOS or TTL logic. SON8-P-0303-0.65 Weight: 0.017 g (typ.) • Built-in protection circuits against overvoltage (active clamp), overtemperature (thermal shutdown), and overcurrent (current limiter). • Low Drain-Source ON-resistance: RDS (ON) = 0.6 Ω (max) (@VIN = 5 V, ID = 0.5 A, Tch = 25°C) • Low Leakage Current: IDSS = 10 μA (max) (@VIN = 0 V, VDS = 30 V, Tch = 25°C) • Low Input Current: IIN = 300 μA (max) (@VIN = 5 V, Tch = 25°C) • “PS-8” package with embossed-tape packing.

Source pin. Input pin. 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. 2 2007-10-02 TPD1044F Timing chart Input signal hysteresis Overcurrent detection Channel temperature Overtemperature detection V(CL)DSS VDD Drain-source voltage Inductive load Drain current Normal Current limiting (limiter) Active clamp Thermal shutdown Note 2: The overtemperature detector circuits feature hysteresis. After overtemperature is detected, normal operation is restored only when the channel temperature falls by the hysteresis amount (5°C typ.) in relation to the overtemperature detection temperature.
