Description: 1-CELL LITHIUM AND LITHIUM POLYMER CHARGE MANAGEMENT IC

Features

* Ideal for Single-Cell (4.1 V or 4.2 V) and Li-Ion or Li-Pol Packs
* Better Than ±1% Voltage Regulation Accuracy With Preset Voltages
* Optional Cell-Temperature Monitoring Before and During Charge
* Integrated Voltage and Current Regulation With Programmable Charge-

Applications

* The AT1457 continuously measures battery temperature using an external thermistor. For safety, the AT1457 inhibits charge until the battery temperature is within user-defined thresholds. The AT1457 then charges the battery in three phases: conditioning, constant current, and constant voltage. If th
