Cost-effective devices are USB-compatible and enable charge currents up to 500 mA

NEW DELHI: Microcontroller and analog semiconductors provider, Microchip Technology Inc. today announced the availability of MCP73811 and MCP73812 (MCP7381X) Li-Ion/Li-Polymer charge-management controllers.

Microchip said in a statement that these single-cell devices would provide integrated charge-management functions, and selectable or programmable charge currents up to 500 mA in a 5-pin SOT-23 package. They are USB compatible and come with integrated current sense, pass transistor and reverse battery protection onboard to enable smaller, more cost-effective designs.

"As more and more applications are beginning to utilise Li-Ion and Li-Polymer batteries, small, low-cost battery-charging solutions are needed," said Bryan Liddiard, vice president of marketing with Microchip's Analog and Interface Products Division. "The MCP7381X chargers support this demand and provide the features necessary for a complete, yet cost-effective, charging solution."
