XC6122E617ER-G

Supervisors Overview

The XC6122E617ER-G is a high-precision voltage detector with watchdog function manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 1.7 V. The device incorporates a CMOS output driver configured as an open-drain type. Key electrical parameters include a typical operating current of 12 µA and a static current of 5 µA. It supports a watchdog timeout period ranging from 50 ms to 1.6 s and offers release delay times between 3.13 ms and 400 ms. The component is housed in a USP-6C package and functions reliably across an industrial temperature range of -40 °C to +85 °C.

Supervisors Feature Summary

• Integrates a watchdog timer function that outputs a reset signal if the input maintains a specific logic level for a defined timeout period.
• Includes an internal EN/ENB pin pull-up mechanism, allowing the watchdog function to be controlled or disabled while the voltage detector remains active.
• Utilizes laser trimming technology to ensure high-precision fixed detect voltages without requiring external adjustment components.

Supervisors Applications

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

Supervisors Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to confirm the specific watchdog timeout and release delay settings, as these vary within the XC6122 series. Ensure the ordering part number matches the required detection voltage of 1.7 V. Confirm package compatibility with the USP-6C footprint during PCB design review.

Supervisors Selection Notes

Select this component when a low-current supervisory circuit with integrated watchdog timing is required for single-input monitoring. The fixed 1.7 V threshold suits applications where precise voltage tracking at lower supply levels is necessary. Consider the internal pull-up on the control pin for simplified interface designs that do not require external biasing resistors for the watchdog enable function.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6122 variant specifically features an internally pulled-up EN/ENB pin, distinguishing it from other series members that may require external control signals. The series utilizes CMOS process technology to achieve low power consumption while maintaining high accuracy through laser-trimmed reference voltages.

Supervisors Replacement Considerations

Cross-reference with other XC6122 series variants such as XC6122E616ER-G or XC6122E618ER-G if different detection thresholds are acceptable. Verify that substitute parts maintain the same USP-6C package and electrical characteristics regarding operating voltage and current consumption.
