Introduction

AI Translation

The MAX8903A–MAX8903E/MAX8903G/MAX8903H/ MAX8903J/MAX8903N/MAX8903Y are integrated 1-cell Li+ chargers and Smart Power Selectors™ 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 onchip. No external MOSFETs, blocking diodes, or current-sense resistors are required.
