Demonstration circuit 1621A features the LTM®8062, a 32V, 2A μModule® power tracking battery charger. The demonstration circuit is designed to operate from a 9.75V to 32V input source, and to charge a 2-cell battery pack to a float voltage of 7.2V.

Demonstration circuits 1645A-A, 1645A-B, 1645A-C and 1645A-D feature the LTM8061, a 32V, 2A μModule® Li-Ion battery charger. Operating from a 6.5V to 32V input source, the 1645A-A and 1645A-B demo circuits charge single cell Li-Ion batteries to float voltages of 4.1V or 4.2V respectively.

This application note is a Ringing Choke Converter (RCC)-based, step-by-step cell phone battery charger design procedure.

The L6924D is a fully monolithic battery charger dedicated to single-cell Li-Ion/Polymer battery packs. It is the ideal solution for space-limited applications, like PDAs, handheld equipment, cellular phones, and digital cameras. It is designed with BCD6 technology and integrates all of the power elements (the Power MOSFET, reverse blocking diode and the sense resistor) in a small VFQFPN16 3mm x …

The MCP7382X Li-Ion Battery Charger Evaluation Board features three circuits utilizing the MCP73826, MCP73827 and MCP73828 devices to demonstrate simple, stand-alone, linear charging of single cell Lithium-Ion/Lithium-Polymer battery packs (the battery packs are not included).

The MCP73833 Li-Ion Battery Charger Evaluation Board is an evaluation and demonstration tool for Microchip’s MCP73833/4 Stand-Alone Linear Li-Ion/Li-Polymer Charge Management Controllers.

There are two independent circuits on the reference design. First circuit is designed with MCP73832, which allows maximum programmable fast charge current up to 500 mA.
