Battery Charger Charging Characteristics
Cycle charge
Current Drain Characteristics
Relationship between Reset and Battery Circuit
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.
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
