2A 1-Cell Li+ DC-DC Chargers for USB and Adapter Power
General Description
The MAX8903A­MAX8903E/MAX8903G/MAX8903Y are integrated 1-cell Li+ chargers and Smart Power SelectorsTM with dual (AC adapter and USB) power inputs.

The switch mode charger uses a high switching frequency to eliminate heat and allow tiny external components. It can operate with either separate inputs for USB and AC adapter power, or from a single input that accepts both. All power switches for charging and switching the load between battery and external power are included on-chip. No external MOSFETs, blocking diodes, or current-sense resistors are required. The MAX8903_ features optimized smart power control to make the best use of limited USB or adapter power. Battery charge current and SYS output current limit are independently set. Power not used by the system charges the battery. Charge current and SYS output current limit can be set up to 2A while USB inpu
