XC6122D750ER-G

Supervisors Overview

The XC6122D750ER-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 5.0 V, indicated by the '750' suffix in the part number. The device utilizes a 6-pin USP-C (UFDFN) package with exposed pad for surface mount installation. It provides an N-channel open-drain output that asserts low when the monitored voltage falls below the threshold. Key electrical characteristics include a typical quiescent current of 5 µA and a maximum operating current of 12 µA. The unit supports a release delay time selection and includes a dedicated watchdog input pin for system monitoring.

Supervisors Feature Summary

• Integrates a voltage monitor with a built-in watchdog timer function using CMOS process technology.
• Features an N-channel open-drain output driver that signals low upon voltage detection.
• Includes an EN/ENB control pin to selectively disable the watchdog function while maintaining voltage monitoring.
• Utilizes laser trimming technology to ensure high precision in internally fixed detect voltages.

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 specific suffix 'ER-G' confirms the 6-USP-C package and tape-and-reel packaging configuration. Ensure the detection voltage code corresponds to the required 5.0 V threshold for the target application. Confirm RoHS compliance status through the official manufacturer datasheet or authorized distributor documentation before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a 5.0 V detection threshold is required for systems operating between 1.0 V and 6.0 V. The integrated watchdog function simplifies design by eliminating external timing components. Consider the low quiescent current for battery-powered applications. Verify that the open-drain output compatibility matches the microcontroller or logic interface requirements of the host system.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors from Torex Semiconductor. The XC6122 variant specifically incorporates the watchdog timer functionality alongside the voltage monitoring circuit. The series is designed for high-precision applications requiring reliable system supervision with minimal external component count.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be disabled by setting the EN/ENB pin to a low or high level, allowing the voltage detector to operate independently while the watchdog remains off.

What is the output state when the detected voltage is normal?

The output type is N-channel open drain. When the monitored voltage is above the detection threshold, the output transistor is off, allowing the line to be pulled high by an external resistor.
