Description
GNDA
76,91
P
Analog ground: This pin should be connected directly to the analog ground plane.
GNDD
1, 40, 75
P
Digital ground: This pin should be connected directly to the digital ground plane.
V3P3A
77
P
Analog power supply: A 3.3V analog power supply should be connected to this pin.
V3P3D
9
P
Digital power supply: A 3.3V digital power supply should be connected to this pin.
VBAT
72
P
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.
V2P5
73
O
Output of the 2.5V regulator. A 0.1F capacitor to GNDA should be connected to this pin.
VLCD

Line Current Sense Inputs: These pins are voltage inputs to the internal A/D con-
verter. Typically, they are connected to the output of a current transformer. Unused
pins must be connected to V3P3A.

Line Voltage Sense Inputs: These pins are voltage inputs to the internal A/D con-
verter. Typically, they are connected to the output of a resistor divider. Unused pins
must be connected to V3P3A.

Comparator Inputs - voltage inputs to the internal comparator: The voltages applied
to these pins are compared to VBIAS. If the voltage is above VBIAS, the corre-
sponding comparator output 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
using an external resistor divider to scale the power supply voltage to a level that
triggers the comparator at the desired voltage drop.
V1: This pin is part of the reset circuitry. It also controls the hardware watchdog
timer. A 0.1F capacitor to GNDA should be connected to this pin.
V2: Comparator input. If unused, this pin must be connected to V3P3A or
ground.
V3: Comparator input, also available to the ADC during alternative multiplexer
cycles. If not used for measuring or sensing purposes, the V3 pin should either
be left unconnected or be connected to the VREF pin. See precautions on page
VBIAS
81
O
9
Reference voltage used by the power fault detection circuit. A 1,000pF capacitor to
GND should be connected to this pin.
VREF
85
I/O
9
Voltage Reference for the ADC. A 0.1F capacitor to GNDA should be connected to
this pin.

Crystal Inputs: A 32kHz style crystal should be connected across these pins.
Typically, a 22-27pF capacitor is also connected from each pin to GNDA. See crystal
manufacturer datasheet for details.
VDRV

O
4
Voltage boost output.
Pin types: P = Power, O = Output, I = Input, I/O = Input/Output
The circuit number denotes the equivalent circuit, as specified under “I/O Equivalent Circuits”.
