BQ24400PWR General Description

The bq24400 is a programmable, monolithic IC for fast-charge management of nickel cadmium (NiCd) and nickel metal-hydride (NiMH) in single or multi-cell applications.

The bq24400 provides these charge termination criteria:

Peak voltage, PVD
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, thebq24400 uses trickle-harge to condition the battery. For NiMH batteries, the bq24400 provides an optional top-off charge to maximize the battery capacity.

The integrated high-speed comparator allows the bq24400 to be the basis for a complete, high-efficiency battery charger circuit for nickel-based chemistries.

Key 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 Voltage (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 Postcharge Maintenance
Built-in Battery Removal and Insertion Detection
Sleep Mode for Low Power Consumption
APPLICATIONS
- Nickel Charger
- High-Power, Multi-Cell Charger
