XC6122D333MR-G

Supervisors Overview

The XC6122D333MR-G is a high-precision voltage detector with watchdog functionality manufactured by Torex Semiconductor. It features a fixed detect voltage of 3.3V and operates within a supply voltage range of 1.0V to 6.0V. The device utilizes CMOS technology, drawing a typical operating current of 12µA and a static current of 5µA. It includes an N-channel open-drain output and supports release delay times ranging from 3.13ms to 400ms. The component is housed in a SOT-25-5 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 for system monitoring
• Features an internal delay circuit eliminating the need for external components for reset timing
• Includes an EN/ENB pin allowing independent control over the watchdog function state

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 latest datasheet to confirm package type and tape-and-reel specifications. Ensure the 3.3V threshold aligns with the target system voltage requirements. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 3.3V detection threshold is required for single-input monitoring. The integrated watchdog function simplifies design compared to separate supervisor ICs. Consider the low quiescent current for battery-operated applications. Verify that the open-drain output configuration matches the downstream logic interface requirements.

Supervisors Part Context

This part belongs to the XC6122 series of voltage detectors from Torex Semiconductor. The series is characterized by high precision achieved through laser trimming technology. These devices are designed for compact designs due to their small footprint and minimal external component count. They serve as critical protection elements in portable electronics and industrial control systems.

Supervisors Replacement Considerations

Cross-reference with other XC6122 variants having different detect voltages if the threshold does not match. Check XC6121 or XC6123 series equivalents for similar form factors but potentially different pinouts or feature sets. Always validate electrical parameters against the original specification sheet.
