I

a 40 kΩ resistor during an overvoltage fault event. The drain pin becomes open circuit when the DR pin is a

logic high or left floating.

FF

O

General fault flag. This pin is an open drain output and is asserted low when overvoltage condition is

detected on any of the source (Sx) pins. Connect this pin to an external supply (1.8 V to 5.5 V) through a 1

kΩ pull-up resistor.

P

Negative power supply. This pin is the most negative power-supply potential. This pin can be connected to

ground in single-supply applications. Connect a decoupling capacitor ranging from 0.1 µF to 10 µF between

Thermal Pad

—

The thermal pad is not connected internally. No requirement to solder this pad. For best performance it is

recommended that the pad be tied to GND or VSS.
