XC6140C20C9R-G

Overview

The XC6140C20C9R-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging. It features a threshold voltage of 2 V and operates within a maximum supply voltage of 6 V. The device provides manual reset functionality with a reset delay time of 224 us. It utilizes an open drain output type and supports one monitored input. The component is housed in an SSOT-24 package, suitable for surface mount installation. It includes a battery backup switch and lacks a watchdog timer. The operational temperature range extends down to -40 C.

Feature Summary

• Voltage monitoring IC optimized for rechargeable battery applications with CV charging
• Manual reset capability with defined delay characteristics
• Battery backup switch integration for power continuity
• Open drain output configuration for flexible interfacing

Applications

• Rechargeable battery voltage monitoring
• Constant voltage charging system supervision
• Power management circuit protection
• Battery backup switching control

Procurement Notes

Verify the specific suffix 'C20' corresponds to the 2 V threshold requirement for your design. Confirm the SSOT-24 package dimensions match your PCB footprint constraints. Ensure the open drain output logic levels are compatible with the downstream microcontroller or system interface. Check availability status as distribution may vary by region.

Selection Notes

Select this component when a 2 V detection threshold is required for single-input voltage monitoring. The open drain output suits systems needing external pull-up resistors. Manual reset is appropriate where software-controlled reset timing is preferred over automatic delays. Verify that the absence of a watchdog timer aligns with the system's safety architecture requirements.

Part Context

This part belongs to the XC6140 series from Torex Semiconductor, specialized for battery monitoring. It differs from other series like XC9140 (boost converters) or XC6132 (different output types). The 'C20' designation specifically indicates the 2.0 V threshold voltage setting within the product family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider checking the official Torex website for updated equivalents or cross-reference lists based on threshold voltage and package compatibility.
