Detects charge current of 23 mA
and switches charge voltage
from 4.9 V to 4.6 V
* Charge current is variable
Current Drain Characteristics
Charging time
(+Vbat circuit current)

Relationship between Reset and Battery Circuit
Battery
voltage
3.3 [V] or higher
Rest voltage 2.8 [V]
The V_Batt 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 V_Batt
circuit operates, and if it is lower than
3.3 [V], it does not start up.
