Power Control Circuit for Battery

Backup Function

SVT

17801

has a battery backup function, and is equipped with a power control circuit allowing for this function.

Battery Backup Function

Three power supply lines are available on the S

, i.e., V

, AV

DD

and RTCV

DD

. V

DD

covers CPU core, log-

ic circuits, and I/O interface circuits, AV

DD

covers analog circuits (ADC), and RTCV

DD

covers RTC and IVRAM.

The battery backup function supplies power only to RTCV

DD

while stopping the power to AV

DD

and V

DD

. This

means that the function stops all operations except operating RTC and retaining contents inside IVRAM with low
power consumption. Because the power is supplied only to the minimum indispensable functions, leak current can
also be reduced drastically compared with sleep mode.

The SVT

17801

is designed to connect the coin battery (CR

2032

) with RTCV

DD

, enabling RTC to keep functioning

and IRAM to retain its contents even if power supply from AC/DC adapter should be stopped.
In normal status, the power is supplied from AC/DC adapter without using the battery.
