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.

Pin Description
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.

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.

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).
