XC6140C21C9R-G

Overview

The XC6140C21C9R-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging capabilities. It features a CMOS output type and operates within a supply voltage range up to 6 V. The device has a threshold voltage of 2.1 V and includes manual reset functionality without a watchdog timer. It utilizes an SSOT-24 package and supports battery backup switching. The reset delay time is specified at 224 us, and it functions reliably across a temperature range from -40 C to +105 C.

Feature Summary

• Integrated constant voltage charging control for rechargeable batteries
• Manual reset capability with defined delay timing
• Battery backup switch support for power continuity
• CMOS output interface for digital logic compatibility

Applications

• Rechargeable battery management systems
• Portable electronic devices requiring voltage supervision
• Consumer electronics with battery backup requirements
• Industrial equipment with wide temperature operation needs

Procurement Notes

Verify the specific suffix codes against official Torex documentation to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Check regional availability as distribution may vary by location. Ensure ESD handling procedures are followed during assembly due to CMOS sensitivity.

Selection Notes

Select this component when a dedicated voltage monitor with integrated CV charging control is required for single-input battery applications. The 2.1 V threshold suits specific lithium-ion or similar cell cutoff requirements. Consider the SSOT-24 footprint for space-constrained designs. Verify that the manual reset feature aligns with system startup sequences rather than automated watchdog dependencies.

Part Context

This part belongs to the XC6140 series of supervisory circuits from Torex Semiconductor. The series focuses on voltage monitoring for portable and industrial applications. The XC6140C21C9R-G specifically denotes the CMOS output variant with a 2.1 V threshold in the SSOT-24 package. It complements other PMIC offerings like LDOs and DC/DC converters in the broader portfolio.

Replacement Considerations

Consult official substitution lists for equivalent threshold voltages. Cross-reference pinouts and electrical characteristics carefully. No direct public substitute part numbers are confirmed in available data.
