Frequently Asked Questions
At what temperature does the MCP73831-2ACI/MC trigger thermal shutdown to protect the device?
The MCP73831-2ACI/MC activates thermal shutdown at 150°C, automatically reducing or stopping charge current to prevent damage to the IC and battery when the junction temperature exceeds this threshold during high-current charging.
Which battery chemistries can the MCP73831-2ACI/MC charge, and does it support single or multi-cell configurations?
The MCP73831-2ACI/MC supports single-cell Li-Ion and Li-Polymer batteries with an adjustable charge termination voltage, making it appropriate for portable devices powered by a single 3.7 V nominal lithium cell such as 18650 or pouch-cell packs.
How does the 8-pin DFN package of the MCP73831-2ACI/MC compare to SOT-23 charger alternatives for space-constrained PCB layouts?
The 8-pin DFN package provides a smaller footprint and better thermal dissipation than SOT-23 alternatives, enabling the MCP73831-2ACI/MC to sustain higher charge currents in a compact PCB area while keeping junction temperature below the 150°C thermal shutdown threshold.
