MAX8845X - 28V Linear Li+ Battery Chargers

This page provides the datasheet information for the MAX8845X, a member of the MAX8845W 28V Linear Li+ Battery Chargers family.

Description

The MAX8845Z/MAX8845Y/MAX8845X/MAX8845W are intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear chargers designed for charging a single-cell lithium-ion (Li+) battery.

Features

  • www. DataSheet4U. com include an active-low control input (EN), an active-low input power source detection output (POK), and a fully charged top-off threshold detection output (CHG). The MAX8845Z/MAX8845Y/MAX8845X/MAX8845W accept an input supply range from 4.25V (4.4V for MAX8845W only) to 28V, but disable charging if the supply voltage exceeds +7.5V (+8.0V for MAX8845X only) to protect against unqualified or faulty AC adapters. The ICs operate over the extended temperature range (-40°C to +85°C).

19-4340; Rev 1; 9/09 KIT ATION EVALU E L B A AVAIL 28V Linear Li+ Battery Chargers with Battery Detection and Overvoltage Protected Output General Description The MAX8845Z/MAX8845Y/MAX8845X/MAX8845W are intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear chargers designed for charging a single-cell lithium-ion (Li+) battery. The MAX8845Z/MAX8845Y/MAX8845X/MAX8845W integrate a current-sense circuit, MOSFET pass element, thermal-regulation circuitry, and eliminate the external reverse-blocking Schottky diode to create the simplest and smallest charging solutions for handheld equipment. The ICs control the charging sequence from the prequalification state through constant current fast-charge, top-off charge, and full-charge indication.
