AAT3696
Description
The AAT3696 Battery Manager™ is a single-cell lithiumion (Li-Ion)/Li-Polymer battery charger IC designed to operate from USB ports or AC adapter up to an input voltage of 6.5V or 6.05V (depending on the option1). For increased safety, the AAT3696 also includes over-voltage input protection (OVP) up to 28V.
The AAT3696 precisely regulates battery voltage after it has reached 4.2V or 4.375V (depending on the option1) Li-Ion/Polymer battery cells through an extremely low RDS(ON) switch. The charging current can be set by an external resistor up to 1.6A. In case an over-voltage condition occurs from the input, a series switch quickly opens and a fault flag is activated to prevent damage to the battery and 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 battery...
