Product Information

Features

  • Safe management of fast charge for NiCd and NiMH battery packs.
  • High-frequency switching controller for efficient and simple charger design
  • Pre-charge qualification for detecting shorted, damaged, or overheated cells
  • Fast-charge termination by peak voltahge (PVD), maximum temperature, and maximum charge time
  • Selectable top-off mode for achieving maximum capacity in NiMH batteries
  • Programmable trickle-charge mode for reviving deeply discharged batteries and for post-charge maintenance
  • Built-in battery removal and insertion detection
  • Sleep mode for low power consumption

Description

The bq24400 is a programmable, monolithic IC for fast-charge management of nickel cadmium (NiCd) and nickel metal-hydride (NiMH) batteries.

The bq24400 provides a number of charge termination criteria:

  • Peak voltage, PVD (for NiCd and NiMH)
  • Maximum temperature
  • Maximum charge time

For safety, the bq24400 inhibits fast charge until the battery voltage and temperature are within user-defined limits. If the battery voltage is below the low-voltage threshold, the bq24400 uses trickle-charge to condition the battery. For NiMH batteries, the bq24400 provides an optional top-off charge to maximize the battery capacity.

The integrated high-frequency comparator allows the bq24400 to be the basis for a complete, high-efficiency power-conversion circuit.
