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--MOS) on each chip. Can directly drive a power load from a CMOS or TTL logic. Weight: 0.08 g (typ.) Built-in protection circuits against overvoltage (active clamp), overtemperature (thermal shutdown), and overcurrent (current limiter). Low Drain-Source ON-resistance: RDS (ON) = 0.4 (max) (@VIN = 5 V, ID = 1 A, Tch = 25C) Low Leakage Current: IDSS = 10 A (max) (@VIN = 0 V, VDS = 20 V, Tch = 25C) Low Input Current: IIN = 300 A (max) (@VIN = 5 V, Tch = -40110C) 8-pin SOP package for surface with embossed-tape packing.

Pin Description
Pin No. 1 2 3 4 Symbol SOURCE1 IN1 SOURCE2 IN2 Source pin 1 Input pin 1 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. 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. Pin Description

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
