Features

z A structure that incorporates Bi-CMOS control circuitry and a power MOSFET (DMOS) on a single chip. z One side of the load can be grounded. z Can be directly driven from a microprocessor. z Overtemperature and load short-circuit (Overcurrent) protections are built in. z Incorporates a diagnosis function that allows diagnosis output to be read externally at load short (Overcurrent), overtemperature. z Low ON- resistance. : R DS(ON) = 0.8Ω (Max) @VDD = 12V, IO = 0.5A, Tch=25℃ z Low supply current. : IDD = 10μA (Max), @VDD = 12V, VIN = 0V, Tch=25℃ z Housed in the PS-8 package and supplied in embossed carrier tape.

Pin No. Symbol Function 1 V DD Power supply pin. 2, 7 N.C No-Connect pin. 3 IN Input pin. The IN pin has an internal pull-down resistor. Even if the IN pin is open, the output will not accidentally turn on. 4 GND Ground pin. 5 MASK Overcurrent detection/protection is IOC(clamp) in the Mask time. If the capacitor and the resistance is not connected to MASK pin, overcurrent protection is IOC(duty). Self-diagnosis detection pin. npn open collector. When Input is “H”(Output on), and Overcurrent or Overtemperature is detected, DIAG becomes low level and it is latched. When input is low level, the state of latch is reseted. 8 OUT Output pin. When a load short-circuit causes an overcurrent (0.8A Min) to flow into a device, output current is limited in order to protect the IC.

Absolute Maximum Ratings (Ta = 25°C) Note: Using continuously under heavy loads (e.g. the application of high temperatur e/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. operatin g 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).

Mask time is decided to prevent discharge electricity by switching-mode overcurrent protection that occur by inrush current. To prevent discharge electricity by overcurrent protection(switching) that operate by inrush current, Mask time is used. Overcurrent protection is clamp current in Mask time from VIN=H. Mask time can roughly set at nether expression. maskR refR1 lnmaskRmaskCmaskt [s] Rref : Internal resistance 110kΩ(typ.) ※ When the Mask time is changed, please change Cmask in the state of Rmask=1MΩ. ※ When overcurrent protection(clamp) is operating, TPD1052F becomes high temperature. Therefore please set Mask time for channel temperature to become 150℃ or less. ※ If you do not use Mask time, please open the MASK pin.
