Microchip's new MCP7381X Li-Ion/Li-Polymer charge-management controllers, offering programmable charge currents up to 500 mA, feature integrated current sense, integrated pass transistor, thermal regulation and reverse battery protection, all in a 5-pin SOT-23 package.
Since they operate within USB output-power limits, the MCP7381X charge-management controllers can be powered via the USB ports on most PCs. The charge-enable input of the new devices provides a very simple interface for designers to use. The MCP73811 has a digital input and selectable USB charge currents of either 100 mA or 500 mA, while the MCP73812 offers a user-programmable charge current via an external resistor.
