Frequently Asked Questions
How is the charge current set on the MCP73832T-2ACI/MC and what is the maximum supported current?
The MCP73832T-2ACI/MC sets its charge current using a single external programming resistor connected to the PROG pin. The maximum programmable charge current is 500 mA, which is appropriate for single-cell Li-Ion batteries commonly found in wearable devices, IoT sensors, and compact consumer electronics requiring fast but safe charging.
What battery chemistry is compatible with the MCP73832T-2ACI/MC, and what is its regulation voltage?
The MCP73832T-2ACI/MC supports single-cell Li-Ion and Li-Polymer batteries. The -2A variant targets a 4.20 V charge regulation voltage, which is the standard termination voltage for most Li-Ion cells. This makes it directly compatible with 3.7 V nominal lithium cells without requiring external voltage references or adjustment components.
How compact is the MCP73832T-2ACI/MC package and how few external components does a typical charger circuit need?
The MCP73832T-2ACI/MC is housed in an 8-pin DFN package with a footprint under 3 mm x 3 mm. A fully functional charger circuit requires only 3 to 4 external components: the programming resistor for charge current, 2 bypass capacitors on the input and output, and optionally a status LED. This makes it one of the lowest component-count single-cell charger solutions available.
