Battery Management

Analog Devices’ high frequency switch mode lithium ion battery charger simplifies constant current control in quick charge portables. The ADP2291 is a constant current/constant voltage linear charger for a single cell Li-ion battery, requiring just a few components to provide a simple and safe charging system that operates from a wide 4.5 V to 12 V input voltage range. The industry’s highest end of voltage accuracy levels are achieved to within ±0.4% at 25°C, ±0.6% at 5°C to 55°C, and ±0.7% at 0°C to 85°C.
