MAX8900A Datasheet 1.2a Switch-mode Li+ Chargers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: EVALUATION KIT AVAILABLE MAX8900A/MAX8900B/MAX8900C 1.2A Switch-Mode Li+ Chargers with ±22V Input Rating and JEITA Battery Temperature.

General Description

The MAX8900_ is a high-frequency, switch-mode charger for a 1-cell lithium ion (Li+) or lithium polymer (Li-Poly) battery.

It delivers up to 1.2A of current to the battery from 3.4V to 6.3V (MAX8900A/MAX8900C) or 3.4V to 8.7V (MAX8900B).

The 3.25MHz switch-mode charger is ideally suited to small portable devices such as headsets and ultra-portable media players because it minimizes ponent size and heat.

Key Features

  • make the MAX8900_ perfect for highreliability systems. The MAX8900_ is protected against input voltages as high as +22V and as low as -22V. Battery protection features include low voltage prequalification, charge fault timer, die temperature monitoring, and battery temperature monitoring. The battery temperature monitoring adjusts the charge current and termination voltage as described in the JEITA.
  • specification for safe use of secondary lithium-ion batteries. Charge parameters are easily a.
