Frequently Asked Questions
What regulated charge voltage does MCP73842T-840I/UN provide for Li-Ion cells?
The MCP73842T-840I/UN provides a preset regulated charge voltage of 4.2 V, which is the standard full-charge voltage for single lithium-ion and lithium-polymer cells. This ensures cells reach maximum capacity without risk of over-voltage damage, making it suitable for portable devices requiring reliable 4.2 V charge termination.
How many charge channels does MCP73842T-840I/UN support and what package does it use?
The MCP73842T-840I/UN supports 1 charge channel and is housed in a compact MSOP-10 (10-pin) package measuring approximately 3 mm x 3 mm. This single-channel configuration with a small 10-pin footprint simplifies PCB routing in space-constrained portable battery charger designs.
When should a designer choose MCP73842T-840I/UN over a simpler linear charger IC?
A designer should choose the MCP73842T-840I/UN when the application requires adjustable safety thresholds alongside 4.2 V regulated charging for dual-cell Li-Ion or Li-Polymer configurations. Unlike basic linear chargers, it integrates battery monitoring functions (JESD-30 code S-PDSO-G10) in a single 10-pin MSOP package, reducing BOM count for wearables, handheld scanners, and medical equipment needing robust charge management within a -40°C to +85°C operating range.
