XC6123C338ER-G

Supervisors Overview

The XC6123C338ER-G is a high-precision voltage detector with a 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 3.3 V. The device utilizes CMOS technology and offers low current consumption, with a typical operating current of 12 µA and static current of 5 µA. It provides an open-drain or open-collector output that goes active low upon detection. The unit includes a built-in delay circuit for release timing and supports a watchdog function with a standard timeout period of 50 ms. It is housed in a compact 6-USP (1.8x2 mm) surface-mount package.

Supervisors Feature Summary

• Integrates a watchdog timer function alongside voltage monitoring capabilities within a single CMOS chip.
• Features a dedicated EN/ENB pin allowing independent control over the watchdog function while maintaining voltage detection operation.
• Provides a built-in delay circuit to generate release delay signals without requiring external components.
• Delivers an active-low output signal via an open-drain or open-collector driver configuration.

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup circuits
• System power-on reset circuits
• Power failure detection systems

Supervisors Procurement Notes

Verify the specific suffix ER-G against the official Torex datasheet to confirm the package type and tape/reel specifications. Ensure the required detection voltage matches the fixed internal setting, as external adjustment is not supported. Confirm RoHS compliance status through the manufacturer's certification documents prior to integration into production designs.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a minimal footprint. The 1.0 V minimum operating voltage makes it suitable for low-voltage battery-powered applications. The availability of an enable pin allows for flexible power management strategies where the watchdog can be disabled independently of the voltage monitor.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series from Torex Semiconductor. These devices are designed for high-precision monitoring using laser-trimmed reference voltages. The series shares common architectural features including low current consumption and integrated delay circuits, differing primarily in detection thresholds and specific feature sets like manual reset or watchdog options.

Supervisors Replacement Considerations

XC6123C338ER-G is part of a series with interchangeable features based on suffix codes. Verify exact electrical parameters against XC6123 series equivalents. No direct cross-manufacturer substitutes are confirmed in public documentation.
