Pin Functions
The following paragraphs give a description of the general
function of each pin.
V
DD
and V
SS
Pins
Power is supplied to the control IC through V
DD
and V
SS
.
V
DD
is the positive supply and V
SS
is the digital and analog
ground. The control IC operates from a single power supply.
Therefore, the conductors to the power supply should be
connected to the V
DD
and V
SS
pins and locally decoupled as
shown in Figure 2.
Figure 2. Recommended Power Supply Connections
OUT Pin
The OUT pin normally provides a digital signal related to
the voltage applied to the voltage comparator and the
threshold level shifted into an 8-bit register from an external
device. When the device is placed in the standby mode the
OUT pin is driven high and will be clocked low when an
overflow is detected from a clock divider (divide by 16384)
driven by the LFO. This allows the OUT pin to wake up an
external device such as an MCU.

OUT Pin During Standby Mode
RST Pin
The RST pin is normally driven high and will be clocked
low when an overflow is detected from total clock divider
(divide by 16,777,216) driven by the LFO. This allows the
RST pin to reset an external device such as an MCU. This
pulse will appear on the RST pin approximately every
52 minutes regardless of the operating mode of the device.
The pulse lasts for two cycles of the LFO oscillator as shown
in Figure 4. Since the RST pin is clocked from the same
divider string as the OUT pin, there will also be a pulse on the
OUT pin when the RST pin pulses every 52 minutes.
