XC6123A342MR-G

Supervisors Overview

The XC6123A342MR-G is a high-precision voltage monitor from Torex Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 3.4 V. The device incorporates an integrated watchdog timer with selectable timeout periods and offers a release delay time of 3.13 ms. It utilizes a CMOS open-drain output configuration and maintains low power consumption with a typical operating current of 12 µA and static current of 5 µA. The component is housed in a compact SOT-25-5 surface-mount package and supports industrial temperature operation from -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer function with configurable timeout periods for system reliability monitoring
• Built-in delay circuit provides release delay without requiring external components
• Low current consumption design suitable for battery-powered and energy-efficient applications
• EN/ENB pin allows independent control of the watchdog function while maintaining voltage detection

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 'MR-G' against the manufacturer's official datasheet to confirm the exact threshold voltage and packaging type. Ensure compatibility with the required operating temperature range and output configuration for the target application. Cross-reference the part number with authorized distributors to validate authenticity and current production status before procurement.

Supervisors Selection Notes

Select this component when a precise voltage threshold near 3.4 V is required alongside integrated watchdog functionality. Consider the low quiescent current for battery-operated devices. Verify that the open-drain output interface matches the microcontroller or logic input requirements. Confirm that the SOT-25-5 package dimensions fit the available PCB space constraints.

Supervisors Part Context

This part belongs to the XC6123 series of voltage detectors manufactured by Torex Semiconductor. The series is characterized by high precision using laser trimming technology and low power consumption CMOS processes. These ICs are designed to replace discrete comparator solutions by integrating reference voltages, delay circuits, and output drivers into a single compact package.

Supervisors Replacement Considerations

Compatible substitutes within the XC6123 series include parts with similar threshold voltages and package types, such as XC6123A341MR-G or XC6123A343MR-G. Verify that any replacement maintains the same watchdog timeout settings and EN/ENB pin functionality to ensure circuit compatibility.
