Overview
AAT3683 1A Linear Li-Ion Battery Charger General Description www.
datasheet4u.
com Features • • • • BatteryManager™ The AAT3683 BatteryManager is a highly integrated single-cell lithium-ion / polymer (Li-Ion) battery charger that operates from a USB port or an AC adapter input up to an input voltage of 6.
5V.
The AAT3683 precisely regulates battery charge voltage and current for 4.
2V Li-Ion battery cells.
The battery charging current can be set by an external resistor up to 1A.
Digital Thermal Loop Control maintains the maximum possible battery charging current for the given set of input to output power dissipation and ambient temperature conditions.
Battery charge state is continuously monitored for fault conditions.
In the event of an over-current, over-voltage, short-circuit, or over-temperature condition, the device will shut down automatically, thus protecting the charging device, control system, and the battery under charge.
A status monitor output pin is provided to indicate the...
