XC6140N21ANR-G

Overview

The XC6140N21ANR-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging capabilities. It features a threshold voltage of 2.1 V and operates within a supply voltage range up to 6 V. The device provides an open-drain output type and includes manual reset functionality without a watchdog timer. It incorporates a battery backup switch and has a reset delay time of 224 us. The component supports single input monitoring and is housed in an SSOT-24 package, suitable for surface mount installation across temperatures from -40 C to +105 C.

Feature Summary

• Integrated constant voltage charging function specifically tailored for rechargeable battery applications
• Manual reset capability allows external control over system initialization states
• Battery backup switch ensures continuous monitoring during power transitions

Applications

• Voltage supervision for lithium-ion or lithium-polymer rechargeable battery packs
• Power management systems requiring manual reset intervention
• Portable electronic devices utilizing constant voltage charging protocols

Procurement Notes

Verify the specific suffix ANR against official Torex documentation to confirm reel packaging and tape specifications. Ensure compatibility with SSOT-24 footprint requirements on target PCB layouts. Cross-reference the 2.1 V threshold setting with system design constraints to prevent false triggering. Confirm RoHS compliance status through current manufacturer declarations before final procurement approval.

Selection Notes

Select this component when manual reset control is required alongside battery voltage monitoring. The fixed 2.1 V threshold suits specific low-voltage cutoff applications. Consider the open-drain output interface for level shifting needs. Evaluate the absence of a watchdog timer against system reliability requirements. Verify thermal performance within the specified operating temperature range for the intended environment.
