The MCP73113, MCP73114 and MCP73213 Lithium-Ion (Li-Ion); and MCP73123, MCP73223 Lithium Iron Phosphate (LiFePO4) Chargers feature high-accuracy voltage regulation and an integrated pass transistor. These two families of charge-management controllers feature Overvoltage Protection (OVP), which prevents overheating and damage to the battery charger circuit from input-voltage spikes. The combination of features enables smaller, safer portable electronic device designs with longer run times for the consumer, medical and industrial markets.

Microchip’s new chargers address increased consumer focus on the safety and efficiency of battery powered applications. All of the new devices have a maximum input voltage of 18V and come with one of two OVP set points – 5.8V and 6.5V for the single-cell MCP73114 and MCP73113/23 chargers; or 13V for the dual-cell MCP73213 and MCP73123 chargers. Additionally, the MCP73113, MCP73114 and MCP73213 devices provide a variety of charging-voltage options for Li-Ion batteries – 4.1 to 4.4V for the single-cell and 8.2 to 8.8V for the dual-cell devices. The MCP73123 and MCP73223 devices target LiFePO4 batteries, and offer charging-voltage options of 3.6 and 7.2V, respectively.

With their unique combination of features and chemistry, the new chargers are ideal for devices in the consumer (e.g. GPS units, portable media players, phone chargers, toys, photo and video cameras, Bluetooth® headsets); medical (e.g. portable glucose meters, blood-pressure and heart-rate monitors); and industrial markets (e.g. point-of-sale terminals, handheld barcode scanners and other portable devices).
