MAX8819A - PMIC

Description

The MAX8819_ is a complete power solution for MP3 players and other handheld applications.

The IC includes a battery charger, step-down converters, and WLED power.

Features

  • an input current-limit switch to power the IC from an AC-to-DC adapter or USB port, a 1-cell lithium ion (Li+) or lithium polymer (Li-Poly) charger, three step-down converters, and a step-up converter with serial step dimming for powering two to six white LEDs. All power switches for charging and switching the system load between battery and external power are included on-chip. No external MOSFETs are required. The MAX8819C offers a sequenced power-up/powerdown of OUT1, OUT2, and then OUT3. Maxi.
