Frequently Asked Questions
What is the maximum programmable charge current for the MCP73833-BZI/UN, and how is it set?
The MCP73833-BZI/UN supports a programmable charge current up to 1 A, set by an external resistor connected to the PROG pin. Selecting the appropriate resistor value allows designers to match charge current to the battery's capacity and thermal requirements.
Does the MCP73833-BZI/UN handle deeply discharged lithium cells, and what preconditioning voltage threshold applies?
Yes. The MCP73833-BZI/UN includes automatic preconditioning that charges deeply discharged cells at a reduced current (typically 10% of the programmed rate) when the cell voltage is below approximately 3 V, preventing cell damage and improving recovery success rate.
How does the MCP73833-BZI/UN's MSOP-10 package compare for board space versus larger DIP or SOIC alternatives?
The 10-pin MSOP package used by MCP73833-BZI/UN has a body footprint of approximately 3 mm × 3 mm, significantly smaller than SOIC-8 or DIP packages. This makes it well-suited for compact IoT and wearable designs where board space is constrained.
What input voltage range is supported, and can the MCP73833-BZI/UN be powered directly from a USB 5 V bus?
The MCP73833-BZI/UN accepts an input voltage from 3.75 V to 6 V, which covers the standard USB 5 V supply. This allows it to be powered directly from a USB bus for single-cell Li-Ion or Li-Polymer battery charging without a separate pre-regulator.
