2 / 12 page TPD1052F 2012-01-20 2 Block Diagram Pin Description Pin No. Symbol Function 1 VDD 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). 6 DIAG 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. VDD OUT 5V regulator Driver Overcurrent Detection Overtemperature Detection DIAG GND IN Diagnosis Logic Logic MASK Mask time IN 12V 5V |
