LA5619M

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
