7.12.21 BAT - External Battery Connector
An optional external battery, connected to BAT, supplies the EBC-C413
board with standby power for the real-time clock and CMOS setup RAM.
Extended temperature lithium batteries are available from WINSYSTEMS,
part numbers:
• BAT-LTC-E-36-16-1
• BAT-LTC-E-36-27-1
A power supervisory circuit contains the voltage sensing circuit and an
internal power switch to route the battery or standby voltage to the
circuits selected for backup. The battery automatically switches on when
the VCC of the systems drops below the battery voltage and off when VCC
returns to normal.
