XC6140C19A9R-G

Overview

The XC6140C19A9R-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging. It features a threshold voltage of 1.9 V and operates within a maximum supply voltage of 6 V. The device utilizes an SSOT-24 package and supports surface mount installation. It includes a manual reset function and a backup battery switch, with a reset delay time of 224 us. The component functions as a single-input voltage monitor with CMOS output type.

Feature Summary

• Integrated backup battery switch functionality for continuous monitoring during power transitions
• Manual reset capability allowing external control over the reset state
• Optimized design for constant voltage charging applications in rechargeable battery systems

Applications

• Voltage monitoring for lithium-ion rechargeable batteries
• Constant voltage charging circuit supervision
• Battery management system power status detection

Procurement Notes

Verify the specific suffix 'C19A9R-G' against the official Torex Semiconductor datasheet to ensure correct threshold voltage and package configuration. Confirm RoHS compliance details and manufacturing date codes prior to ordering. Check regional availability restrictions as distribution may vary by location. Ensure the SSOT-24 footprint matches the target PCB design requirements.

Selection Notes

Select this component when a dedicated voltage monitor for CV-charged batteries is required. The 1.9 V threshold suits specific cell chemistry levels. Consider the SSOT-24 package size constraints. Verify if the manual reset feature aligns with the system's fault recovery strategy. Compare against other XC6140 variants if different thresholds or output types are needed.
