Test Circuit PIN FUNCTION DESCRIPTIONS Pin No. Mnemonic Function 1 FORCE 2 Output of Channel 2 control amplifier to gate of external N-channel MOSFET. 2 SENSE 2 Input from source of external MOSFET to inverting input of Channel 2 control amplifier, via output voltage-setting feed- back resistor network. 3 SHDN2 Digital Input. Active-low shutdown control with 50 µA internal pull-up. The output of Channel 2 control amplifier goes to ground when SHDN2 is taken low. 4 GND Device Ground Pin. 5 SHDN1 Digital Input. Active-low shutdown control with 50 µA internal pull-up. The output of Channel 1 control amplifier goes to ground when SHDN1 is taken low. 6 SENSE 1 Input from source of external MOSFET to inverting input of Channel 1 control amplifier, via output voltage-setting feedback resistor network. 7 FORCE 1 Output of Channel 2 control amplifier to gate of external N-channel MOSFET. 8VCC 12 V Supply. PIN CONFIGURATION TOP VIEW (Not to Scale) 8 7 6 5 1 2 3 4 FORCE 2 SENSE 2 SHDN2 GND VCC FORCE 1 SENSE 1 SHDN1 ADM1052 CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADM1052 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. WARNING! ESD SENSITIVE DEVICE |
