Relationship between Reset and Battery Circuit
Battery voltage Rest voltage 2.8 [V] 3.3 [V] or higher
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.
