Procurement Notes

Verify the specific suffix 'C9R' against official Torex documentation to confirm package type and reel specifications. Ensure environmental compliance requirements match project standards by checking RoHS details in the datasheet. Confirm availability status as distribution channels may indicate restricted supply or regional limitations for this specific part number variant.

Selection Notes

Select this component when constant voltage charging integration is required alongside voltage monitoring. The 2.2 V threshold suits specific lithium-ion cell protection levels. Verify that the SSOT-24 package fits the PCB layout constraints. Ensure the manual reset feature aligns with system recovery logic requirements rather than automatic watchdog implementations.

Part Context

This part belongs to the XC6140 series of supervisory circuits manufactured by Torex Semiconductor. The series focuses on battery management applications requiring precise voltage detection and charging control integration. The XC6140 family provides various threshold options and package configurations to accommodate different portable device designs and power management architectures.

Replacement Considerations

Consult the official XC6140 series datasheet for direct pin-compatible alternatives with adjusted threshold voltages. Verify that substitute parts maintain the same SSOT-24 package dimensions and CMOS output characteristics to ensure mechanical and electrical interchangeability without redesigning the host circuit board.
