2 / 18 page ![]() PD166019T1F Preliminary R07DS0730EJ0100 Rev.1.00 Page 2 of 16 Apr 25, 2012 Block Diagram Load GND OUT GND IN VIN RIN RL Von VCC VCC VOUT IL Temp Sensor OUT voltage Detector Internal Power supply Low Voltage (Open) Detector ESD Off SW Control Logic Current Detector Current Sense Pin Arrangement 1 Tab (Top view) 2345 VCC IN OUT GND VCC Pin Function Pin No. Pin Name Function 1 VCC Supply voltage: pin1 and 5 must be externally connected 2 IN Input: activate the power switch by direct drive of output MOSFET 3/Tab OUT Output to load: Tab and pin 3 are internally connected 4 GND Ground pin Note 5 VCC Supply voltage: pin1 and 5 must be externally connected Note: In case of necessity to eliminate the destruction by the soldering bridge to VCC: Pin#5, insert a resistor RGND (recommended 1 k max) between GND pin and system ground. In this condition, current flaws out to IN pin. R IN is recommended 2 k min. GND to IN current = (RGND 1 mA – 0.6 V) / RIN |
