NiMH Charger IC with alkaline cell detection in tiny TQFN package

Maxim's DS2710 is a stand-alone, NiMH charger IC with alkaline-cell detection.
This charger IC packed in TQFN package features fast-charge control and alkaline-cell detection and protect system damage due to corrosive cell leakage.
The DS2710 is smart enough to work without microcontroller with specifically made for AA or AAA size battery charging.
Suitable applications are, MP3 players, voice recorders, handheld games, toys, and any other application capable of using standard-size alkaline or NiMH batteries where battery can be charged through USB port.

The output is regulated using a switch-mode or linear control scheme. The device offers comprehensive charge control for fast-charging NiMH cells, including precharge conditioning, negative-delta-V fast-charge termination, and top-off charging. Voltage, temperature, and charge-timer monitoring during all charge phases provides redundant secondary charge-termination methods for additional protection against overcharge. Additionally, a status pin drives an LED to indicate precharge, fast-charge, or fault conditions.

Package: 3mm x 4mm, 10-pin TQFN package
Price: start at $1.52 for 1000 pieces.
