MCP73838T-NVI/UN

Overview

The MCP73838T-NVI/UN is a single-cell lithium-ion or lithium-polymer battery charge management controller manufactured by Microchip Technology. It supports input voltages from 3.75 V to 6 V and delivers an output current of 1200 mA with selectable termination voltages of 4.2 V, 4.35 V, 4.4 V, or 4.5 V. The device operates within a temperature range of -40°C to +85°C and is housed in a 10-lead MSOP package.

Feature Summary

• Integrates auto-discharge function for safe battery storage
• Supports USB and DC power source inputs
• Indicates charging status via dedicated LED driver pin

Applications

• Portable electronic devices requiring single-cell Li-Ion/Polymer charging
• USB-powered consumer electronics
• Battery backup systems for embedded controllers

Procurement Notes

Verify the suffix 'NVI' against official Microchip documentation to confirm the specific termination voltage selection (4.2V, 4.35V, 4.4V, or 4.5V) and package variant. Ensure compatibility with system thermal requirements for the MSOP-10 package. Cross-reference datasheet revision history for any functional updates prior to final design implementation.

Selection Notes

Select this component when a compact solution for single-cell lithium battery charging is required with integrated auto-discharge capabilities. It is suitable for designs powered by standard USB or low-voltage DC sources where precise voltage regulation and charging status indication are necessary.

Part Context

This part belongs to the MCP7383x family of charge management controllers. It shares architectural similarities with the MCP73837 and MCP73833 but offers distinct feature sets regarding auto-discharge and input switching configurations tailored for portable applications.

Replacement Considerations

MCP73838T-FJI/UN: Verify if the FJI suffix matches the required termination voltage and package type. MCP73838T-FCI/UN: Confirm package compatibility and electrical parameter alignment.
