XC6140C16CNR-G

Overview

The XC6140C16CNR-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging. It features a detection voltage of 3.60V and an output type of Active Low, Open Drain. The device operates within a supply voltage range of 1.5V to 6.0V. It includes a built-in delay circuit to prevent false triggering during power-up. The component supports operation across a temperature range of -40°C to +85°C and is housed in an SOT-24-4 package.

Feature Summary

• Integrated voltage monitoring specifically optimized for rechargeable battery applications with constant voltage charging profiles.
• Built-in delay circuit functionality ensures stable operation by preventing erroneous output signals during power-on transitions.

Applications

• Rechargeable battery voltage supervision
• Constant voltage charging system monitoring
• Portable electronic device power management

Procurement Notes

Verify the specific suffix 'C16' corresponds to the required 3.60V detection threshold before procurement. Confirm that the Open Drain output configuration aligns with the target circuit's pull-up requirements. Ensure the SOT-24-4 package dimensions fit the designated PCB footprint. Cross-reference the operating temperature range with the application environment specifications to guarantee reliability under thermal stress conditions.

Selection Notes

Select this component when precise monitoring of rechargeable battery voltages is required during constant voltage charging phases. The integrated delay feature makes it suitable for systems sensitive to transient power fluctuations. Choose this part over standard detectors if the application demands a dedicated solution for battery management rather than general-purpose voltage supervision. Consider the Open Drain output compatibility with downstream logic levels.

Part Context

This part belongs to the XC6140 series from Torex Semiconductor, which specializes in voltage monitors tailored for battery-powered devices. Unlike generic voltage detectors, this series incorporates features relevant to battery charging cycles. The XC6140C16CNR-G represents a specific variant within this family, distinguished by its fixed detection voltage and output characteristics.

Replacement Considerations

Direct substitutes must match the 3.60V detection threshold, Open Drain output, and SOT-24-4 package. Verify functional equivalence regarding the internal delay circuit timing. Generic voltage detectors may lack the specific optimization for constant voltage charging scenarios found in this series.
