MAX8903J - 2A 1-Cell Li+ DC-DC Charger

Download the MAX8903J datasheet PDF. This datasheet also covers the MAX8903A variant, as both devices belong to the same 2a 1-cell li+ dc-dc charger family and are provided as variant models within a single manufacturer datasheet.

Description

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.

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.

EVALUATION KIT AVAILABLE MAX8903A–E/G/H/J/N/Y 2A 1-Cell Li+ DC-DC Chargers for USB and Adapter Power General Description 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.
