Overview
DATA SHEET AAT3698 1.
6A Linear Li-Ion Battery Charger in a 3x3 TDFN Package General Description The AAT3698-1/-2 BatteryManager™ is a single-cell lithium-ion (Li-Ion)/Li-Polymer battery charger IC designed to operate from a USB port or AC adapter with an input voltage of up to 7.
0V.
For increased safety, the AAT36981/-2 also includes over-voltage input protection (OVP) up to 28V.
The AAT3698-1/-2 precisely regulates battery voltage for 4.
2V Li-Ion/Polymer battery cells through a low RDS(ON) switch.
The charging current can be set by an external resistor up to 1.
6A.
If an over-voltage condition occurs from the input, the series switch quickly opens and a fault flag is activated, preventing damage to the battery and the charging circuitry.
Other fault conditions are monitored in real time.
In case of an over-current, battery over-voltage, short circuit, or over-temperature failure, the device will automatically shut down, thus protecting the charging device, control system, and the batt...
