MAX1924 Datasheet Advanced Li+ Battery-pack Protectors

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2278; Rev 0; 4/02 Advanced Li+ Battery-Pack Protectors General.

General Description

The MAX1894/MAX1924 are lithium-ion/lithium-polymer (Li+) battery-pack protector ICs for 3- or 4-series Li+ battery packs.

The MAX1894/MAX1924 enhance the useful operating life of Li+ batteries by monitoring individual cell voltages and preventing over/undervoltage conditions.

The MAX1894/MAX1924 also protect the battery pack against charge current, discharge current, and packshort fault conditions.

Key Features

  • All protection thresholds and delays do not require any external components and are trimmed at the factory. If any cell voltage drops below the undervoltage threshold, the MAX1894/MAX1924 disconnect the pack from the load and power down to prevent deep discharge of the pack. The MAX1894/MAX1924 offer a trickle-charge feature, which provides a low-current path to safely charge a deeply discharged pack. The MAX1894/ MAX1924 also have two logic-level inputs, which can be used by a microcontroller.
