Key Features
- 1A maximum charge current with USB/DC input auto-switch enabling seamless charging from both 5V USB ports and DC adapters without external switching circuitry
- Adjustable charge threshold via external resistor allows fine-tuning of termination voltage for different Li-Ion or Li-Polymer cell chemistries
- Compact MSOP-10 (10-pin small outline) package with integrated thermal regulation reduces external component count and PCB area in portable charger designs
Applications
The MCP73838-FJI/UN is designed for single-cell lithium-ion and lithium-polymer battery charging in portable electronics such as smartphones, tablets, portable medical monitors, and Bluetooth accessories. Its USB/DC auto-switch feature makes it especially suitable for devices that need to charge from both a wall adapter and a standard 5V USB port without user intervention. The adjustable threshold and 1A charge current capability allow it to serve a wide range of battery capacities from small coin cells to larger 3000 mAh packs.

Frequently Asked Questions
What is the maximum charge current supported by the MCP73838-FJI/UN and how is it set?
The MCP73838-FJI/UN supports a maximum charge current of 1A, programmable via an external resistor connected to the PROG pin. Designers can set currents below 1A by selecting the appropriate resistor value, allowing the charger to be matched to the battery capacity and USB port current limit, such as 500 mA for standard USB 2.0 ports.
How does the USB/DC auto-switch feature on MCP73838-FJI/UN benefit portable device designs?
The USB/DC input auto-switch on MCP73838-FJI/UN automatically selects between a 5V USB source and an external DC adapter without requiring additional switching components or firmware control. This simplifies the power path design in portable devices, reducing BOM count and PCB area while ensuring the device correctly charges from either source at up to 1A.
What package does MCP73838-FJI/UN use and how does it assist in minimizing PCB footprint for wearable applications?
The MCP73838-FJI/UN is housed in a MSOP-10 (10-pin micro small outline) package with a very small body, which is well suited for wearable devices and compact IoT nodes that have stringent PCB area constraints. The integrated charge control, thermal regulation, and input switching in this single 10-pin package eliminates several discrete components, shrinking the overall charger circuit footprint to under 50 mm² in typical designs.
