TPD1044F
Toshiba Intelligent Power Device
TPD1044F
Silicon Monolithic Power MOS Integrated Circuit
Low-Side Switch for Motor, Solenoid and Lamp Drive
The TPD1044F is a 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
* A monolithic power IC with a new structure combining a control block and a vertical power MOSFET (L2--MOS) on single 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). SON8-P-0303-0.65 Weight: 0.017 g (typ.)

Pin Description
Pin No. 1,2,3,6,7,8 4 5 Symbol DRAIN SOURCE IN Pin Description Drain current is limited (by current limiter) if it exceeds 1 A (min) in order to protect the IC. Source pin. Input pin. 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.

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).
Note 3: Drive operation: Mounted on glass epoxy board [25.4mm x 25.4mm x 0.8mm]
Note 4: Active clamp capability (single pulse) test condition VDD = 40 V, Tch = 25C(initial), L = 50 mH, IAR = 1 A, RG = 25 Note 5: Repetitive rating, pulse width limited by maximum channel temperature.
