MCP73832T-2DFI/OT

Overview

The MCP73832T-2DFI/OT is a single-cell lithium-ion and lithium-polymer charge management controller manufactured by Microchip Technology. It operates within a supply voltage range of up to 6V and delivers a fixed output voltage of 4.2V. The device supports a maximum output current of 500mA and is housed in a SOT-23-5 surface-mount package. It functions across an operating temperature range from -40°C to +85°C.

Feature Summary

• Fully integrated charge management controller for single-cell lithium-ion and lithium-polymer batteries
• Includes thermal regulation to reduce charging current during high-temperature operation
• Provides status indication via dedicated logic pins for charge state and fault conditions

Applications

• Portable consumer electronics requiring single-cell battery charging
• Mobile communication devices
• Personal digital assistants and handheld gadgets

Procurement Notes

Verify the specific suffix '2DFI' corresponds to the required 4.2V output and 500mA current rating. Confirm the 'OT' suffix indicates the correct tape-and-reel packaging format. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the datasheet revision date with your design timeline.

Selection Notes

Select this component when a compact SOT-23-5 footprint is required for single-cell Li-Ion or Li-Po applications. It is suitable for designs needing integrated thermal regulation without external sensing resistors. Compare against the MCP73831 series if different output voltages or current limits are necessary. Ensure the input power source can support the 6V maximum operating voltage specification.

Part Context

This part belongs to the MCP73831/2 family of charge management controllers designed for portable applications. It shares architectural similarities with other members like the MCP73831T-2ACI/OT but differs in specific electrical parameters such as output current capacity. The family is characterized by minimal external component count and built-in safety features.

Replacement Considerations

The MCP73831T-2ACI/OT serves as a functional substitute within the same product family, offering similar integration levels. Verify that the alternative part's output voltage and current ratings align with the target battery specifications before substitution.
