XC6123F532MR-G

Supervisors Overview

The XC6123F532MR-G is a high-precision voltage monitor with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 3.2 V. The device utilizes CMOS technology, drawing a typical operating current of 12 µA and a standby current of 5 µA. It provides an active-low open-drain output and includes a backup switch function. The reset delay time is typically 400 ms, while the watchdog timeout period is also specified at 400 ms. It functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with a built-in watchdog timer for comprehensive system supervision.
• Features a low current consumption design suitable for battery-powered applications, utilizing CMOS process technology.
• Includes an ON/OFF control pin (EN/ENB) allowing independent management of the watchdog function while maintaining voltage monitoring.

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup systems
• Power failure detection in electronic equipment

Supervisors Procurement Notes

Verify the specific suffix 'F' corresponds to the required 400 ms reset delay and watchdog timeout parameters. Confirm that the SOT-25 package orientation matches the PCB footprint requirements. Ensure the 3.2 V threshold aligns with the target supply rail. Check RoHS compliance documentation for final assembly standards. Validate that the open-drain output configuration is compatible with the downstream logic levels.

Supervisors Selection Notes

Select this component when a fixed 3.2 V detection threshold and a 400 ms timing response are required. The F-series designation specifically indicates the 400 ms delay characteristics compared to other series variants. Consider the low static current for power-sensitive designs. Verify that the single-input monitoring capability meets the system architecture needs without requiring external comparators.

Supervisors Part Context

This part belongs to the XC6123 series, which groups high-precision voltage detectors with watchdog functions. The series shares common architectural features such as laser-trimmed thresholds and internal delay circuits. Differentiation between series members primarily relies on the alphanumeric suffixes defining specific threshold voltages and timing delays. This model represents a specific configuration within the broader PMIC supervisor family offered by Torex.

Supervisors Replacement Considerations

XC6123F532MR-G is the precise identifier for this configuration. Other XC6123 variants may share the package but differ in threshold voltage or delay times. Direct substitution requires matching the 3.2 V threshold and 400 ms timing specifications exactly. Generic supervisors lack the integrated watchdog functionality and specific timing profiles defined in the official datasheet.
