Key Features

  • Adjustable charge termination threshold enables customization for different Li-Ion and Li-Polymer cell chemistries
  • Programmable charge current up to 1 A via single external resistor for flexible battery sizing
  • Integrated thermal regulation loop reduces charge current when junction temperature approaches 110°C
  • Compact DFN-10 package (3 mm × 3 mm) with low 6-week lead time for portable product designs

Applications

The MCP73833-FCI/MF is used in portable consumer electronics, IoT edge devices, and wearables that require reliable single-cell Li-Ion or Li-Polymer charging from a USB or wall-adapter source. Its adjustable termination threshold and programmable current make it flexible for custom battery packs ranging from small 100 mAh cells to larger 2000 mAh packs. Medical monitoring devices and handheld industrial instruments also benefit from its thermal protection and compact footprint.

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.
