status

A doubled level of VSS1 is applied to the

input of the constant voltage circuit.

Operating

range

–1.8 to –3.5 V

Current

consumption

0.75 mA*

Feature

When the battery level is powered down, a

smaller operating voltage margin is gained,

compared to the case of Figure 3.

* When the software duty is about 5%
