XC6122D634MR-G

Supervisors Overview

The XC6122D634MR-G is a high-precision voltage detector with watchdog functionality manufactured by Torex Semiconductor. It operates within an input voltage range of 1 V to 6 V and features a fixed detection threshold of 3.4 V. The device incorporates CMOS 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 reset timing. The component supports a watchdog timer function controlled via an EN/ENB pin and is housed in a compact SOT-25-5 package.

Supervisors Feature Summary

• Integrates a watchdog timer function with ON/OFF control capability via the EN/ENB pin
• Features a built-in delay circuit that eliminates the need for external components for release delay
• Provides low current consumption suitable for battery-powered applications
• Utilizes laser trimming technology for precise internal voltage detection thresholds

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 'D' indicates the correct detection voltage and timeout characteristics against the official datasheet. Confirm the package marking matches the SOT-25-5 form factor. Ensure the order quantity aligns with standard reel packaging requirements if applicable. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and current production status before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog protection is required. It is suitable for designs needing a 3.4 V threshold and operation up to 6 V. Consider the low quiescent current for energy-sensitive applications. Verify that the open-drain output configuration meets the system logic level requirements. Ensure the thermal performance fits within the specified -40°C to +85°C operating temperature range.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These ICs are designed using CMOS process technology to offer high precision and low power consumption. The series is characterized by internally fixed detect voltages and multiple watchdog timeout settings, providing a flexible solution for supervisory applications without requiring extensive external circuitry.

Supervisors Replacement Considerations

Check for other XC6122 variants with different detection voltage suffixes if the 3.4 V threshold does not match the target application. Verify compatibility with alternative supervisors offering similar open-drain outputs and watchdog functions.
