Frequently Asked Questions
How is the charge current set on the MCP73833T-FCI/MF, and what is the maximum programmable value?
The charge current on the MCP73833T-FCI/MF is set by a single resistor on the PROG pin, with a maximum programmable fast-charge current of 1 A. A 1 kΩ resistor typically sets 1 A, while higher resistance values reduce the current proportionally, allowing designers to fine-tune charge rate to match their battery's C-rate without firmware changes or digital interfaces.
Does the MCP73833T-FCI/MF support USB charging standards, and how does it limit input current?
Yes, the MCP73833T-FCI/MF supports USB-compatible input current limits of 100 mA for USB suspend mode and 500 mA for standard USB operation, selectable via the USB pin logic level. This built-in compliance eliminates the need for an external current-limiting circuit, making the device a drop-in solution for any USB-powered portable product that must conform to USB 2.0 power specifications.
For a compact wearable design, how does the MCP73833T-FCI/MF's DFN-10 package compare to alternative charger ICs in SOIC packages?
The DFN-10 package measures approximately 3 mm × 3 mm, which is roughly 4 times smaller in footprint than a typical SOIC-8 charger IC. For wrist-worn wearables and in-ear devices with strict PCB area budgets, this size reduction translates directly into more space for the battery or antenna, while the 1 A maximum charge current still delivers fast enough charging to keep the user experience competitive.
