Battery backup is not implemented on IGEPv2-RA and IGEPv2-RB.
You can use i2c external rtc or connect externally a super-cap/rechargable battery on R768 pins. But it could be unpopulated R768 is 0 Ohm resistor connected between GND and BKBAT (M14) input from TPS65950and connect externally a super-cap/rechargable battery on R768 pads. Also you can use i2c external rtc. <br><br>IGEPv2-RC has available an unpopulated super-cap/rechargable battery footprint (BT741) for real time clock backup batter. battery<br>
