Battery Charger Charging Characteristics
Cycle charge
Current Drain Characteristics
Relationship between Reset and Battery Circuit
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.
Current limiting with current limiter
Charge current characteristics
Charge voltage characteristics
Detects charge current of 23 mA
and switches charge voltage
from 4.9 V to 4.6 V
* Charge current is variable
Trickle charge
