TPD1024S
TOSHIBA Intelligent Power Device
Silicon Monolithic Power MOS Integrated Circuit
TPD1024S
Low-side Power Switch for Motors, Solenoids, and Lamp Drivers
The TPD1024S is a monolithic power IC for low-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 is equipped with an intelligent self-protection function.
Features
z A monolithic power IC with a new structure combining a control block
and a vertical power MOS FET (π-MOS) on a single chip
z Can directly drive a power load from a CMOS logic.
z Built-in protection against overvoltage, load short-circuiting, and
thermal shutdown
z Low on-resistance : RDS (ON) = 0.5 Ω(max), (@VIN = 5 V, Tj = 25°C)
z 3-pin power-molded package usable for surface mounting.

Function
1
IN
Input pin.
Input is CMOS-compatible, with pull-down resistor connected. Even if the input is open, output will not
accidentally turn on.
2
OUT
Output pin.
When current in excess of the typical current (3.5 A (typ.)) flows to the output pin, the current limiter
operates to protect the IC.
3
GND
Ground pin.

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).
