MCP73832-2DCI/MC

Battery Chargers Overview

The MCP73832-2DCI/MC is a single-cell lithium-ion or lithium-polymer battery charge management controller manufactured by Microchip Technology. It operates within a supply voltage range of 3.75 V to 6 V and provides a regulated charging output of 4.2 V for the battery cell. The device supports a maximum programmable constant-current charging rate of 500 mA. It is housed in an 8-DFN (2x3) surface-mount package with exposed pad, suitable for thermal dissipation. The component is rated for operation across an ambient temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Implements standard CC/CV charging algorithm for single-cell Li-ion and Li-polymer batteries
• Integrates thermal regulation to reduce charging current when die temperature exceeds safe limits
• Includes automatic recharge function that resumes charging when battery voltage drops below threshold
• Provides status indicator output to signal charging completion or fault conditions

Battery Chargers Applications

• Portable electronic devices requiring single-cell lithium battery charging
• Consumer electronics with limited PCB space constraints
• Battery-powered instrumentation and sensors
• Medical devices utilizing lithium-based power sources

Battery Chargers Procurement Notes

Verify the specific suffix 'MC' corresponds to the 8-DFN (2x3) package configuration as documented in the official datasheet. Confirm the '2' designation indicates the 4.2 V fixed output voltage setting. Ensure compatibility with the target board's thermal design requirements due to the exposed pad package type. Cross-reference the manufacturer part number against the latest revision history to ensure no functional changes have occurred since the original specification release.

Battery Chargers Selection Notes

Select this component when designing circuits for single-cell lithium chemistry applications requiring a compact solution. The 8-DFN package offers a smaller footprint compared to traditional SOT-23 options, making it suitable for space-constrained designs. The integrated thermal regulation feature reduces the need for external temperature sensing components. Verify that the system input voltage remains within the specified 3.75 V to 6 V operating range to ensure proper functionality and protection.

Battery Chargers Part Context
