Relationship between Reset and Battery Circuit

Battery

voltage

3.3 [V] or higher

Rest voltage 2.8 [V]

The VBatt circuit operates at the edge

where the reset voltage becomes Hi.

(At this time, the output transistors are

set on and the load is put on; If this

voltage is 3.3 [V] or higher, the VBatt

circuit operates, and if it is lower than

3.3 [V], it does not start up.

No. 5673-3/8
