XC6122A641ER-G

Supervisors Overview

The XC6122A641ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 4.1 V. The device utilizes a 6-USPC (1.8x2 mm) package with an exposed pad. Key electrical parameters include a typical reset timeout of 800 ms, an operating temperature range of -40°C to +85°C, and a low quiescent current consumption. The output configuration is open drain or open collector with active-low reset signaling.

Supervisors Feature Summary

• Integrates a watchdog timer function that triggers a reset if the input signal remains static for a specified duration.
• Features an enable pin (EN/ENB) that allows independent control of the watchdog function while maintaining voltage monitoring.
• Utilizes laser trimming technology to ensure high precision in the internal reference voltage detection thresholds.
• Provides built-in delay circuits for release delay times without requiring external components.

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 codes against the official datasheet to confirm the exact detection voltage and watchdog timeout period. Ensure the ordering information matches the required package type and thermal characteristics. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a compact solution combining voltage supervision and system integrity monitoring is required. The fixed 4.1 V threshold suits applications where this specific voltage level serves as the critical trip point. Consider the 6-USPC package dimensions for PCB layout constraints and verify that the open-drain output compatibility aligns with the downstream logic levels.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The 'XC6122' designation indicates the inclusion of a watchdog timer function, distinguishing it from basic voltage monitors. The series is characterized by CMOS process technology, offering low current consumption and high accuracy across the industrial temperature range.

Supervisors Replacement Considerations

Cross-reference with other XC6122 series variants such as XC6122A741ER-G or XC6122D319ER-G if different detection voltages or timeout periods are needed. Verify pinout compatibility and package dimensions before substituting to ensure mechanical fit and electrical functionality remain unchanged.
