Frequently Asked Questions
What does the adjustable threshold feature of the MCP73833-FCI/MF enable compared to fixed-threshold charger ICs?
The adjustable threshold allows designers to set the charge termination voltage between 4.1 V and 4.2 V, accommodating Li-Ion cells from different manufacturers with slightly different chemistry requirements. This flexibility reduces the need for multiple SKUs in a product line supporting various battery suppliers.
How is the charge current of the MCP73833-FCI/MF configured, and what range is supported?
Charge current is set by a single external resistor connected to the PROG pin. The programmable range spans approximately 100 mA to 1 A, allowing the same IC to serve designs from compact wearables with 200 mAh cells up to portable tools with 2000 mAh battery packs.
In a USB-powered wearable with a 500 mAh cell, how does thermal regulation affect charging time?
At a programmed 500 mA charge current, the MCP73833-FCI/MF targets approximately 1 hour to full charge. If PCB thermal resistance is high and junction temperature approaches 110°C, the thermal regulation loop automatically reduces current, extending charge time but protecting both the IC and the 500 mAh cell from thermal damage.
How does MCP73833-FCI/MF compare to MCP73833-NVI/MF for procurement and design interchangeability?
Both parts share the same DFN-10 package and 1 A maximum charge current, but differ in ordering suffix indicating pre-programmed configuration options. The MCP73833-FCI/MF has a 6-week factory lead time versus 3 weeks for the NVI variant, so designers in high-volume production should plan inventory around the longer lead time or qualify both variants as drop-in replacements.
