XD6130A251MR-Q

Supervisors Overview

The XD6130A251MR-Q is a voltage detector manufactured by Torex Semiconductor, designed for monitoring a single input voltage. It features an open-drain output and supports both manual reset and watchdog timer functions. The device operates within a supply voltage range of up to 6V and has a threshold voltage of 2.5V. It is housed in a SOT-26-6 package and is rated for operation between -40°C and +125°C. The component includes a backup switch function and offers high accuracy.

Supervisors Feature Summary

• Integrates a watchdog timer with externally adjustable timeout period
• Includes a battery backup switch function for data retention
• Supports manual reset capability via external control
• Provides open-drain output compatible with various logic levels

Supervisors Applications

• Portable electronic devices requiring low power supervision
• Battery-operated systems needing backup switching
• Microcontroller reset circuits with watchdog functionality
• Automotive electronics meeting AEC-Q100 Grade 1 standards

Supervisors Procurement Notes

Verify the specific suffix MR-Q indicates automotive qualification (AEC-Q100) and RoHS compliance as per official datasheets. Confirm the threshold voltage code corresponds to 2.5V. Ensure the ordering information matches the exact package type SOT-26-6. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check for any specific handling or storage requirements listed in the product documentation.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog and backup functions is required. It is suitable for applications demanding high accuracy and wide operating temperature ranges. Consider the open-drain output configuration for interface compatibility. Evaluate the need for manual reset versus automatic reset based on system design. Verify that the 6V maximum supply voltage meets the input requirements.

Supervisors Part Context

This part belongs to the XD6130 series of supervisory circuits from Torex Semiconductor. The series is characterized by ultra-low current consumption and small package sizes. The XD6130 variants typically include watchdog timers and backup switches, making them distinct from basic voltage detectors. This specific model is optimized for automotive and industrial applications due to its extended temperature range and reliability standards.

Supervisors Replacement Considerations

Check for XD6130A251MR-G if automotive qualification is not strictly required. Verify functional equivalence with other Torex XD6130 variants having similar threshold voltages. Ensure substitute parts support the same SOT-26-6 package and pinout. Confirm that replacement options maintain the open-drain output and watchdog functionality.
