XC6123A327ER-G

Supervisors Overview

The XC6123A327ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.6V to 5.0V and features a fixed detection threshold of 3.27V. The device utilizes CMOS technology for low current consumption and includes a built-in delay circuit, eliminating the need for external components for release delay timing. It provides an N-channel open-drain output and supports ON/OFF control of the watchdog function via the EN/ENB pin.

Supervisors Feature Summary

• Integrates a watchdog timer function with manual reset capability for system monitoring
• Features an internal delay circuit that generates release delay signals without external components
• Includes an enable pin (EN/ENB) to selectively disable the watchdog function while maintaining voltage detection
• Utilizes laser trimming technology to ensure high precision in fixed detect voltage settings

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 corresponds to the required tape and reel packaging configuration. Confirm the detection voltage code A327 aligns with the target 3.27V threshold requirement. Ensure the USP-6 package dimensions match the PCB footprint design constraints. Validate RoHS compliance status against current regulatory requirements for the intended market.

Supervisors Selection Notes

Select this component when a fixed 3.27V threshold is required for voltage supervision. Choose this part if the application demands independent control over the watchdog timer activation via the EN/ENB pin. This IC is suitable for designs requiring minimal external component count due to its integrated delay circuitry. Consider the operating temperature range of -40°C to +85°C for environmental compatibility.

Supervisors Part Context

This device belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The series shares common architectural features including CMOS process integration and low current consumption characteristics. Variations within the series primarily differ in detection voltage thresholds and output configurations, allowing for flexible implementation across various power management applications.

Supervisors Replacement Considerations

Cross-reference XC6123A327E with potential equivalents from other manufacturers offering similar watchdog voltage detectors. Verify that substitute parts maintain the same 3.27V threshold accuracy and USP-6 package outline dimensions. Ensure functional compatibility regarding the EN/ENB pin logic levels and open-drain output structure.
