Li-Ion System PPM Reference Design

WHAT IS THE LI-ION BATTERY CHARGER SYSTEM POWER PATH
MANAGEMENT REFERENCE DESIGN?
The Li-Ion Battery Charger System Power Path Management Reference Design
demonstrates the features of Microchip’s MCP73832 “Miniature Single-Cell, Fully Inte-
grated Li-Ion, Li-Polymer Charge Management Controllers” and MCP73833 “Miniature
Single-Cell, Fully Integrated Li-Ion, Li-Polymer Charge Management Controllers” with
the load sharing system power path management capability.
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.
Note:
Please refer to Table 2-1 for Charge Status Outputs and Table 2-2 for
charge current setups.
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.
The Li-Ion Battery Charger System Power Path Management Reference Design is
designed to observe the performance and features on the circuits via multiple test
points. Circuits can also be implemented into suitable applications without additional
work.
