battery greater than 2V. If the backup__ battery is
below 2V or V
CCl
falls below V

Battery Output. During normal operation, the
BAT output supplies up to 1mA of continuous
battery current. In shipping mode, the BAT
output is high impedance.

Battery-Disconnect Input. The RST input is used
to prevent battery discharge during shipping.
Pulsing the RST input disconnects the battery
