MCP73833T-NVI/MF

Overview

The MCP73833T-NVI/MF is a linear single-cell lithium-ion or lithium-polymer battery charge management controller manufactured by Microchip Technology. It operates within an input supply voltage range of 3.75 V to 6 V and delivers a maximum output current of 1.2 A. The device provides a precise charging termination voltage of 4.2 V. It is housed in a compact 10-lead DFN package measuring 3 mm by 3 mm with a height of 0.88 mm, designed for surface-mount installation. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates complete linear charge management functions including constant-current and constant-voltage regulation stages.
• Incorporates thermal regulation circuitry that automatically reduces charging current when die temperature approaches safe limits.
• Features a status output pin indicating the completion state of the charging cycle.
• Supports programmable charge current setting via a single external resistor.

Applications

• Portable consumer electronics requiring single-cell Li-Ion or Li-Po power sources
• Mobile communication devices such as smartphones and tablets
• Handheld medical instruments and diagnostic equipment
• IoT edge devices and sensor nodes

Procurement Notes

Verify the specific suffix 'NVI' against official Microchip documentation to confirm the exact output voltage tolerance and factory trim specifications. Ensure the ordering quantity matches the tape-and-reel packaging requirements specified in the datasheet. Confirm RoHS compliance status and moisture sensitivity level ratings prior to final procurement decisions.

Selection Notes

Select this component for designs requiring high integration and minimal external passive components. The fixed 4.2 V output makes it suitable for standard single-cell lithium batteries. Consider the thermal performance of the DFN package relative to the PCB copper area available for heat dissipation during high-current charging operations.

Part Context

This part belongs to the MCP73833 family of charge management controllers, which are designed for simple, cost-effective battery charging solutions. The family typically includes variants with different packages and voltage accuracies. The 'T' designation indicates tape-and-reel packaging, while 'MF' specifies the DFN package type and material composition.
