Overview

The BENCHMARQ BQ2004H is a sophisticated switch-mode battery charger IC designed for single to four-cell NiCd and NiMH battery packs, capable of delivering up to 2A charge current. Its core strength lies in its intelligent temperature monitoring, incorporating hot and cold profile thermistor inputs to optimize charge termination and prevent overcharging or undercharging, a critical factor often overlooked in simpler linear chargers where thermal runaway is a significant concern. This standalone controller offers flexibility through RC-settable parameters, simplifying integration into cost-sensitive designs while maintaining robust battery management.

Key Features

Supports 1-4 Series Cells (NiCd, NiMH)
Maximum Charge Current: 2A
Integrated Battery Temperature Thermistor Monitoring (Hot/Cold Profile)
Input Voltage Range: 4.5V to 5.5V
Standalone Control Topology (RC-Settable)
Package: 16-SOIC (Dimensions: 9.9mm x 7.5mm x 1.6mm)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Fast charging of portable power tools with NiMH battery packs
Smart battery management in medical devices requiring precise charge termination
Robust charging solutions for industrial handheld equipment
Temperature-compensated charging in remote sensor nodes
