Description
Analog ground: This pin should be connected directly to the analog ground
plane.
Digital ground: This pin should be connected directly to the digital ground plane.
Analog power supply: A 3.3V analog power supply should be connected to this
pin.
Digital power supply: A 3.3V digital power supply should be connected to this
pin.
Battery backup power supply. A battery or super-capacitor is to be connected
between VBAT and GNDD. If no battery is used, connect VBAT to V3P3D.
Output of the 2.5V regulator. This pin should be terminated with a 0.1μF
capacitor.

Description
Line Current Sense Inputs: These pins are voltage inputs to the internal A/D
converter. Typically, they are connected to the output of a current transformer.
Line Voltage Sense Inputs: These pins are voltage inputs to the internal A/D
converter. Typically, they are connected to the output of a resistor divider.
Comparator Inputs: These pins are voltage inputs to the internal comparator. The
voltages applied to these pins are compared to an internal reference voltage VBIAS
(1.5V). If the input voltage is above the reference, the corresponding comparator out-
put will be high (1). The outputs are maintained in the COMP_STAT register. A typical

application is to sense the voltage on the DC supply. An external resistor divider is
used to scale the power supply voltage to a level that triggers the comparator at the
desired voltage drop. A 0.1μF capacitor to GNDA should be connected to the V1 pin.
If not used, the V3 pin should be left unconnected or connected to VREF.

Reference voltage used by the power fault detection circuit.
Voltage Reference for the ADC. A 0.1μF capacitor to GNDA should be connected to
this pin.
Crystal Inputs: A 32kHz style crystal should be connected across these pins.
Typically, a 10pf capacitor is also connected from each pin to GNDA. See crystal
manufacturer datasheet for details.
