MAX1507 - Linear Li Battery Charger

Description

The MAX1507 is an intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear charger for a single-cell lithium-ion (Li+) battery.

Features

  • include the charging status (CHG) of the battery and an active-low control input (EN). The MAX1507 accepts a +4.25V to +13V supply, but disables charging when the input voltage exceeds +7V to protect against unqualified or faulty AC adapters. The MAX1507 operates over the extended temperature range (-40°C to +85°C) and is available in a compact 8-pin thermally enhanced 3mm x 3mm Thin DFN package with 0.8mm height. Features.
  • Stand-Alone Linear 1-Cell Li+ Battery Charger.
  • No Ext.

www.DataSheet.co.kr 19-2899; Rev 1; 11/03 KIT ATION EVALU E L B AVAILA Linear Li+ Battery Charger with Integrated Pass FET and Thermal Regulation in 3mm x 3mm Thin DFN General Description The MAX1507 is an intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear charger for a single-cell lithium-ion (Li+) battery. The MAX1507 integrates the current-sense circuit, MOS pass element, and thermal-regulation circuitry, and also eliminates the reverse-blocking Schottky diode to create the simplest and smallest charging solution for hand-held equipment. The MAX1507 functions as a stand-alone charger to control the charging sequence from the prequalification state through fast-charge, top-off charge, and fullcharge indication.
