XC6122F632ER-G

Supervisors Overview

The XC6122F632ER-G is a high-precision voltage detector with a watchdog function manufactured by Torex Semiconductor. It operates within an input voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 3.2 V. The device utilizes CMOS technology, drawing a typical operating current of 12 µA and a static current of 5 µA. It provides an N-channel open-drain output and includes a built-in delay circuit for release timing. The component supports a watchdog timeout period of 400 ms and a reset delay time of 400 ms. It is housed in a USP-6C package and functions reliably across a temperature range of -40 °C to +85 °C.

Supervisors Feature Summary

• Integrates a watchdog timer with selectable timeout periods and a built-in delay circuit for release timing without external components
• Features an EN/ENB pin that allows independent control over the watchdog function while maintaining voltage detection operation
• Utilizes laser trimming technology to ensure high-precision detection voltages with low temperature characteristics
• Provides an N-channel open-drain output configuration suitable for direct interfacing with microprocessor reset lines

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 codes against the official datasheet to confirm the exact detection voltage, watchdog timeout, and delay time parameters. Ensure the ordering code matches the required USP-6C package and RoHS compliance status. Cross-reference the manufacturer's latest documentation to validate the part number before procurement to avoid specification mismatches.

Supervisors Selection Notes

Select this component when a precise voltage threshold of 3.2 V is required alongside integrated watchdog functionality. The low current consumption makes it suitable for battery-powered applications. Consider the USP-6C package size for space-constrained designs. Verify that the open-drain output logic levels are compatible with the target system's input requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors from Torex Semiconductor. The series is characterized by high precision and low current consumption using CMOS process technology. These devices are designed to provide reliable power management supervision for embedded systems and digital logic circuits.

Supervisors Replacement Considerations

XC6122F632ER-G may be substituted with other parts in the XC6122 series that share the same detection voltage and package, provided the watchdog timeout and delay times match the application requirements. Verify pin compatibility and electrical specifications before replacement.
