XC6124A543ER-G

Supervisors Overview

The XC6124A543ER-G is a single-channel watchdog circuit manufactured by Torex Semiconductor Ltd. It features a voltage threshold of 4.3V and provides an open-drain or open-collector output. The device operates within a temperature range of -40°C to 85°C and utilizes a 6-USPC (1.8x2) surface-mount package. A typical reset timeout of 400 ms ensures reliable system supervision.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system monitoring
• Configurable open-drain or open-collector output interface
• Wide operating temperature range for industrial environments

Supervisors Applications

• Industrial equipment system supervision
• Consumer electronics power management
• Embedded systems reset monitoring

Supervisors Procurement Notes

Verify the specific suffix ER-G against official Torex documentation to confirm pinout and package dimensions. Ensure compatibility with existing PCB footprints, as variations exist within the XC6124 family. Cross-reference the manufacturer's latest datasheet to validate electrical characteristics and thermal performance specifications before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a dedicated watchdog timer with a fixed 4.3V threshold is required. The choice depends on the need for a compact 6-USPC package and support for both PWM and PFM control modes in broader system designs. Consider the open-drain output capability for flexible logic interfacing requirements in low-power applications.

Supervisors Part Context

This part belongs to the XC6124 series of supervisor circuits from Torex Semiconductor. The series includes variants with different thresholds and packages, such as the XC6124C and XC6124D models. These components are designed for voltage monitoring and reset generation in portable and industrial devices requiring high reliability.

Supervisors Replacement Considerations

Direct substitutes include other XC6124 series variants like XC6124A743MR-G or XC6124C343ER-G, provided the voltage threshold and package type match the design requirements. Verify functional equivalence regarding reset timeout and output configuration before substitution.
