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.

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!
