MCP73213T-A6AI/MF

Battery Chargers Overview

The MCP73213T-A6AI/MF is a linear battery charger controller designed for dual-cell lithium-ion or lithium-polymer battery packs. It operates within an input supply voltage range of 4.2 V to 13 V and delivers an adjustable output current between 130 mA and 1.1 A. The device provides a fixed output voltage of 8.4 V, suitable for charging two series-connected cells. It features overvoltage protection (OVP) for the battery pack and is housed in a 10-pin DFN-10 surface-mount package with an exposed pad for thermal management.

Battery Chargers Feature Summary

• Integrated overvoltage protection circuitry safeguards dual-cell battery packs against excessive charging voltages.
• Linear regulation architecture enables precise control of charge current and termination for lithium-based chemistries.
• Supports operation across industrial temperature ranges from -40 °C to +85 °C.

Battery Chargers Applications

• Charging dual-cell lithium-ion battery packs in portable electronic devices
• Power management systems for consumer electronics requiring OVP protection
• Industrial equipment utilizing series-connected lithium polymer batteries

Battery Chargers Procurement Notes

Verify the specific suffix 'A6AI' matches the required output voltage and pin configuration before procurement. Confirm that the reel packaging aligns with automated assembly requirements. Ensure compatibility with the target PCB footprint for the DFN-10 package. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions.

Battery Chargers Selection Notes

Select this component when designing circuits for dual-series cell configurations requiring integrated overvoltage protection. The adjustable current limit allows optimization for different battery capacities. Consider the thermal performance of the DFN-10 package relative to the maximum expected charge current and ambient operating conditions.

Battery Chargers Part Context

This part belongs to the MCP73213 family of battery chargers. Variants such as MCP73213-A6SI/MF differ primarily in output voltage specifications, such as 8.4 V versus 8.2 V or 8.85 V, corresponding to different cell count or chemistry requirements. The 'T' prefix indicates tape-and-reel packaging, while 'MF' denotes the specific package style.

Battery Chargers Replacement Considerations

Direct substitutes include other MCP73213 variants like MCP73213-A6SI/MF or MCP73213-B6SI/MF, provided the output voltage tolerance matches the application needs. Verify that alternative parts maintain the same DFN-10 footprint and pinout to ensure mechanical compatibility without PCB redesign.
