XC6122C528ER-G

Supervisors Overview

The XC6122C528ER-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 detect voltage of 2.8 V. The device utilizes CMOS process technology, drawing a typical operating current of 12 µA and a static current of 5 µA. It provides an open-drain output and includes a built-in delay circuit for release delay times. The component is housed in a USP-6C package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods
• Features internal laser trimming for precise voltage detection settings
• Includes EN/ENB pin for independent control of the watchdog function

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 corresponds to the USP-6C package and reel packaging configuration. Confirm the detect voltage code matches the required threshold. Ensure RoHS compliance documentation is available for the manufacturing batch. Cross-reference the datasheet revision date to confirm parameter stability before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a low-current supervisor with integrated watchdog functionality is required. The fixed 2.8 V threshold suits applications monitoring 3.3 V or similar logic rails. The USP-6C package offers a compact footprint for space-constrained designs. Verify that the open-drain output compatibility aligns with the downstream logic interface requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The series is characterized by high precision and low power consumption using CMOS technology. The XC6122 variant specifically incorporates the watchdog feature, distinguishing it from basic voltage monitors. The ER-G suffix indicates surface-mount packaging suitable for automated assembly processes.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned ON or OFF via the EN/ENB pin. Setting this pin to a specific level disables the watchdog while keeping the voltage detector operational.

What is the output configuration?

The device features an open-drain output type, which requires an external pull-up resistor to function correctly in most circuit configurations.
