Toshiba Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit
TPD1038F
Motor, Solenoid, Lamp Drivers
High-side Power Switch
The TPD1038F is a monolithic power IC for high-side switches.
The IC has a vertical MOS FET output which can be directly
driven from a CMOS or TTL logic circuit (e.g., an MPU). The
device offers intelligent self-protection and diagnostic functions.
Features
• A monolithic power IC with a structure combining a control
block (Bi-CMOS) and a vertical power MOS FET on a single
chip.
• One side of load can be grounded to a high-side switch.
• Can directly drive a power load from a microprocessor.
• Built-in protection against overheating and load
short-circuiting.
• Incorporates a diagnosis function that allows diagnosis output to be read externally at load short-circuiting,
opening, or overheating.
• Up to -(50-VDD)～ -(60-VDD) of counterelectromotive force from an L load can be applied.
• Low on-resistance : RDS(ON)=120mΩ(max) ( @ VDD = 12 V、Ta = 25℃、Io = 2 A)
• 8-pin SOP package for surface mounting that can be packed in tape
Pin Assignment Marking

Pin Description
Pin No. Symbol Function
1 OUT
Output pin. When the load is short-circuited and current in excess of the detection current (3A min)
flows to the output pin, the output automatically turns on or off.
2 GND Ground pin.
3 DIAG
Self-diagnosis detection pin.Goes low when overheating is detected or when output is short circuit
with input on (high). N-channel open drain.
4 IN
Input pin. Input is CMOS compatible, with pull down resistor connected. Even if the input is open,
output will not accidentally turn on.

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).
