XC6140N19ANR-G

Overview

The XC6140N19ANR-G is a voltage monitoring integrated circuit designed for rechargeable battery applications with constant voltage charging capabilities. It features a single input channel and an open-drain output type. The device operates within a supply voltage range of up to 6 V and includes manual reset functionality without a watchdog timer. It incorporates a backup switch for battery retention. The reset delay time is specified at 224 us. The component supports surface mount installation in an SSOT-24 package and functions across a temperature range from -40 C to +105 C.

Feature Summary

• Integrated voltage monitoring specifically optimized for rechargeable batteries with constant voltage charging support
• Includes manual reset capability and a dedicated backup switch for maintaining battery data
• Provides open-drain output interface compatible with CMOS logic levels

Applications

• Monitoring voltage levels in lithium-ion or lithium-polymer rechargeable battery packs
• System supervision in portable electronic devices requiring battery charge management
• Power failure detection in embedded systems utilizing constant voltage charging protocols

Procurement Notes

Verify the specific suffix ANR-G against the manufacturer's latest datasheet to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required threshold voltage of 1.9 V for the target application. Cross-reference the SSOT-24 package dimensions with PCB footprint libraries to prevent assembly errors. Confirm RoHS compliance status if environmental regulations apply to the end product.

Selection Notes

Select this component when a dedicated monitor for rechargeable batteries with CV charging integration is required. The open-drain output allows flexible interfacing with various microcontrollers. Consider the 224 us reset delay for timing-sensitive sequences. Evaluate the operating temperature range suitability for harsh environments. Compare against other XC6140 series variants if different threshold voltages are needed.

Part Context

This part belongs to the XC6140 series of supervisory circuits manufactured by Torex Semiconductor. These ICs are categorized under PMIC and power management solutions. The series focuses on low-power voltage monitoring for battery-operated equipment. The specific model distinguishes itself through its specialized support for rechargeable battery charging cycles and backup functionality.

Replacement Considerations

Other XC6140 series variants such as XC6140C20ANR-G or XC6140N18ANR-G offer similar functionality with different threshold voltages. Verify that the replacement maintains the same SSOT-24 package and open-drain output configuration. Ensure the new part supports the required manual reset and backup switch features.
