XC6122E749MR-G

Supervisors Overview

The XC6122E749MR-G is a high-precision voltage monitor manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 4.9 V. The device incorporates a watchdog timer function with a typical reset delay time of 200 ms. It utilizes CMOS technology for low current consumption, drawing 5 uA in static mode and 12 uA during operation. The output driver is configured as an open-drain type. The component is housed in a compact SOT-25-5 surface-mount package and is rated for industrial temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer function for system reliability monitoring
• Built-in delay circuit eliminates the need for external timing components
• Low power consumption suitable for battery-operated applications
• High-precision detection voltage established via laser trimming

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 official Torex datasheet to confirm the package style and RoHS compliance status. Ensure the detection voltage code corresponds to the required 4.9 V threshold for your design. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and avoid counterfeit components.

Supervisors Selection Notes

Select this component when a precise 4.9 V threshold is required for supervisory applications. The integrated watchdog feature simplifies design by removing external timing parts. Consider the 1 V minimum operating voltage for compatibility with single-cell lithium batteries or lower voltage rails. Verify that the open-drain output configuration matches the logic levels of the connected microcontroller.

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 provide high precision and low current consumption. The series offers various detection voltages and package options to support diverse power management requirements in portable and industrial electronics.

Supervisors Replacement Considerations

Check for other XC6122 variants with different detection voltages if the 4.9 V threshold does not match the target application. Verify pinout compatibility before substituting with other supervisor ICs from different manufacturers.
