XC6122F635ER-G

Supervisors Overview

The XC6122F635ER-G is a high-precision voltage detector with a watchdog function manufactured by Torex Semiconductor. It features an N-channel open-drain output and operates within a supply voltage range of 1.0V to 6.0V. The detect voltage is fixed at 3.5V using laser trimming technology. The device includes a built-in delay circuit for release delay times ranging from 3.13ms to 400ms and offers six selectable watchdog timeout periods between 50ms and 1.6s. It utilizes CMOS process technology for low current consumption, with typical operating current of 12μA and static current of 5μA.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods to monitor system activity
• Features an internal EN/ENB pin that allows independent control of the watchdog function while maintaining voltage detection
• Utilizes laser trimming technology to ensure high precision in fixed detect voltage settings
• Provides an N-channel open-drain output configuration suitable for direct interfacing with logic circuits

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 datasheet to confirm package type and environmental compliance. Ensure the detect voltage code matches the required 3.5V threshold for your application. Cross-reference the part number with the manufacturer's latest documentation to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 3.5V detection threshold is required alongside integrated watchdog capabilities. Consider the USP-6C package for space-constrained designs. Evaluate the available watchdog timeout options to match the microprocessor's clock speed and expected response time. Verify that the open-drain output compatibility aligns with the downstream logic levels in the target system design.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These devices are designed for applications requiring precise voltage monitoring and system reset management. The series shares common architectural features including CMOS construction and low power consumption characteristics, differentiated primarily by detect voltage thresholds and package variations.

Supervisors Replacement Considerations

Check for other XC6122 variants with different detect voltages if 3.5V is not strictly required. Verify pinout compatibility with existing PCB layouts when substituting with similar supervisor ICs from other manufacturers.
