XC6122D717ER-G

Supervisors Overview

The XC6122D717ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0V to 6.0V and features a fixed detection threshold of 1.70V with a typical hysteresis width of VDF x 5%. The device utilizes laser trimming technology for accurate voltage setting and includes a built-in delay circuit that eliminates the need for external components. It offers selectable watchdog timeout periods ranging from 50ms to 1.6s and release delay times from 3.13ms to 400ms, housed in a compact 6-pin USP package.

Supervisors Feature Summary

• Integrates a high-precision voltage monitor with a watchdog timer function using CMOS process technology
• Features internally fixed detect voltages set via laser trimming technology for high accuracy
• Includes a built-in delay circuit for reset signal release without requiring external components
• Provides ON/OFF control capability for the watchdog function via the EN/ENB pin

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-and-reel configuration. Ensure the detection voltage code D717 corresponds to the required 1.70V threshold for your application design. Cross-reference the manufacturing date code and RoHS compliance status with current distributor documentation before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a low quiescent current supervisor with integrated watchdog functionality is required. The fixed 1.70V threshold suits applications monitoring 1.8V or 3.3V logic rails where precise brown-out protection is necessary. The open-drain output allows flexible interfacing with various microprocessor reset lines. Consider the operating temperature range of -40°C to +85°C for industrial or consumer electronics environments.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These devices are designed for portable equipment and battery-operated systems due to their low current consumption. The series differentiates itself by combining voltage monitoring with watchdog timing in a single small footprint, reducing board space compared to discrete solutions.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned off while the voltage detector remains active by setting the EN/ENB pin to a low or high level. For the XC6122 series, this pin is internally pulled up to VIN, allowing it to be left open if the watchdog is always enabled.

What determines the reset release delay time?

The release delay time is determined by the internal delay circuit and is available in five selectable ranges from 3.13ms to 400ms. This ensures stable output signals without requiring external capacitors.
