Description
Line Current Sense Inputs: These pins are voltage inputs to the internal
A/D converter. Typically, they are connected to the outputs of current
sensors. Unused pins must be connected to V3P3A .

Line Voltage Sense Inputs: These pins are voltage inputs to the internal
A/D converter. Typically, they are connected to the outputs of resistor
dividers. Unused pins must be connected to V3P3A.
Comparator Input: This pin is a voltage input to the internal comparator.
The voltage applied to the pin is compared to the internal BIAS voltage
(1.6 V). If the input voltage is above VBIAS, the comparator output is high
(1). If the comparator output is low, a voltage fault occurs. A series 5 k ?
resistor should be connected from V1 to the resistor divider.
VREF

Voltage Reference for the ADC. Normally disabled and left unconnected.
If enabled, a 0.1 ? F capacitor to V3P3A should be connected to this pin.

Crystal Inputs: A 32 kHz crystal should be connected across these pins.
Typically, a 33 pF capacitor is also connected from XIN to GNDA and a
15 pF capacitor is connected from XOUT to GNDA. It is important to
minimize the capacitance between these pins. Refer to the crystal
manufacturer data sheet for details. If an external clock is used, a 150
mV P-P clock signal should be applied to XIN, and XOUT should be left
unconnected.

Pin types: P = Power, O = Output, I = Input, I/O = Input/Output
The circuit number denotes the equivalent circuit, as specified under Section 5 I/O Equivalent Circuits .
