MCHPMCP73831T-2DCI/MC
Overview
The MCP73831T-2DCI/MC is a compact linear charge management IC for single-cell rechargeable batteries. It is commonly used to build simple Li-ion or Li-poly charging circuits from a USB or other 5 V source. The device is intended for space-constrained portable products where a small external component count matters.
Why Choose This Part
This family is popular because it is simple to design in and needs relatively few external parts. It is well suited to small PCB layouts where cost, board area, and engineering time matter. For engineers building single-cell rechargeable products, it provides a practical charge-management block without the complexity of a multi-cell charger.
Applications
Getting Started
Use the Microchip datasheet as the primary design reference and follow the recommended application circuit closely, especially for the charge current programming and battery connection details. For evaluation, start from a known-good reference schematic or a development board that includes an MCP73831-based charger stage, then verify thermal behavior and charge current on your final PCB. If you are integrating it into a USB-powered design, make sure the upstream 5 V source can supply the selected charge current plus any system load.
