MCP7383XRD-PPM (#2): 1A, Li-Ion Single Cell

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. The second circuit is designed with MCP73833, which allows maximum programmable fast charge current up to 1A and has a power good indicator and an additional status output. Two preset values of fast charge current are available for each circuit by a SPDT dip on the board for users to experience different speed.

Both circuits come with load sharing system power path management feature. This feature allows a DC Power Source to support system load while charging a Li-Ion battery. When the DC Power Source is absent, the Li-Ion battery will support system load and stop charging.

A number of device options allow the MCP73832 and the MCP73833 to be utilized in a variety of applications. Please refer to the MCP73832 data sheet (DS21984) and MCP73833 data sheet (DS22005) for device options.
