Frequently Asked Questions
What regulated charge voltage does the MCP73832-3ACI/MC provide for Li-Polymer cells?
The MCP73832-3ACI/MC delivers a fixed regulation voltage of 4.35V, which is tailored for modern high-capacity Li-Ion and Li-Polymer cells that require a higher end-of-charge voltage compared to the standard 4.2V cells.
How is charge current configured in MCP73832-3ACI/MC-based designs?
Charge current is set by a single external resistor connected to the PROG pin. Selecting a 2kΩ resistor programs approximately 500mA, while a 10kΩ resistor sets roughly 100mA, giving designers flexibility to match any battery capacity without changing the IC.
In which portable product categories is the MCP73832-3ACI/MC most commonly designed in?
This IC is widely used in Bluetooth earbuds, fitness trackers, smart badges, and IoT sensor nodes that run from small single-cell Li-Polymer packs. Its 8-pin DFN footprint and minimal external component count make it a frequent choice for PCBs with tight area budgets under 100mm².
