MCP73833T-BZI/MF

Battery Chargers Overview

The MCP73833T-BZI/MF is a standalone linear charge management controller designed for lithium-ion and lithium-polymer batteries. It operates within an input voltage range of 3.75 V to 6 V and supports output currents up to 1200 mA. The device provides precise charging termination at voltages including 4.2 V, 4.35 V, 4.4 V, and 4.5 V. Packaged in a 10-pin DFN (3x3 mm) with an exposed pad, it functions reliably across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrated thermal regulation that dynamically reduces charging current to limit die temperature during high-power or high-ambient conditions
• Automatic recharge capability that resumes charging when battery voltage drops below the programmed threshold after full charge completion
• Status indicator function that signals charge status through an external LED connection

Battery Chargers Applications

• Portable consumer electronics requiring safe lithium-ion battery charging
• Medical devices utilizing lithium-polymer power sources
• Industrial handheld equipment operating in varied environmental temperatures

Battery Chargers Procurement Notes

Verify the specific suffix BZI/MF corresponds to the required output voltage setting and tape-and-reel packaging configuration. Confirm the 10-pin DFN footprint matches your PCB layout constraints. Ensure compatibility with the intended input supply voltage range before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when a compact solution for single-cell Li-Ion or Li-Po charging is required. It is suitable for designs needing integrated thermal protection without external sensing resistors. Consider the 1200 mA output limit against maximum battery capacity requirements.

Battery Chargers Part Context

This part belongs to the MCP73833 family of charge management controllers from Microchip Technology. It serves as a complete solution for charging single-cell lithium-based batteries, eliminating the need for external current sense resistors or complex monitoring circuits.

Battery Chargers Replacement Considerations

Direct substitutes include other variants within the MCP73833 series such as MCP73833T-CNI/MF or MCP73833T-AMI/MF, provided the package type and electrical specifications align with the design requirements.
