Li+ Charger Protection IC

General Description

The APL3213/A provide Li+ charger protection against

over-voltage. The IC is designed to monitor input voltage.

When input voltage is over the threshold, the IC removes

the power from the charging system by turning off an in-

ternal switch. The protection also have deglitch time

against false triggering due to voltage spikes. The

APL3213/A also provide Power-On-Reset (POR) function

and over-temperature protection. The Power-On-Reset

circuit monitors supply voltages to prevent wrong

operations. The over-temperature protection limits the

junction temperature below 140oC in case of short circuit

or overload conditions.
