TPD1039S TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS IC TPD1039S Low-Side Switch for Motor, Solenoid and Lamp Drive TPD1039S is a monolithic power IC for 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 offers intelligent self-protection functions. Features • A monolithic power IC with a new structure combining a control block and a vertical power MOSFET (π-MOS) on a single chip. • Can directly drive a power load from a CMOS or TTL logic. • Built-in protection circuits against overvoltage, overheat, and overcurrent. Weight: 0.36 g (typ.) • Low ON-resistance: RDS (ON) = 0.25 Ω (max) (@VIN = 5 V, Tch = 25°C) • Package TO-92 (MOD) can be packed in tape.

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. Output pin. The current limit for output current is 5 A (typ.) when excessive current flow into a device because of in-rush current and short load of a lamp. Ground pin.

Note 3: Overtemperature protection will work when the channel temperature exceeds 125°C. Be sure to operate the device in such a way that the channel temperature does not exceed 125°C. Note4: 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).

Be sure to operate the device in such a way that the channel temperature does not exceed 125°C. The overtemperature protection function protects a device from destruction. Once started, however, this function will operate continuously; device reliability is not guaranteed while the function is in operation.
