XD6131B301MR-Q

Supervisors Overview

The XD6131B301MR-Q is a voltage detector manufactured by Torex Semiconductor, designed for monitoring single input voltages. It features an open-drain output and includes a watchdog timer with an externally adjustable timeout period. The device operates within a supply voltage range up to 6 V and provides a reset delay time of 100 ms. It is housed in a SOT-26-6 package and supports surface mount installation. The component is rated for operation between -40°C and +125°C and holds AEC-Q100 Grade 1 qualification.

Supervisors Feature Summary

• Includes a watchdog timer with externally adjustable timeout functionality
• Features a battery backup switch for maintaining state during power loss
• Provides open-drain output configuration for flexible interfacing

Supervisors Applications

• Automotive electronic systems requiring AEC-Q100 compliance
• Industrial equipment power supply monitoring
• Consumer electronics voltage supervision

Supervisors Procurement Notes

Verify the specific threshold voltage corresponds to the required application level, as the series offers multiple options. Confirm that the open-drain output type aligns with the system's pull-up requirements. Ensure the SOT-26-6 package footprint matches the PCB design. Check that the external components for the watchdog timer are compatible with the specified operating temperature range.

Supervisors Selection Notes

Select this part when AEC-Q100 Grade 1 automotive qualification is mandatory. Choose the XD6131 series over non-watchdog variants if system stability monitoring is required. Consider the 100 ms reset delay for timing constraints. Verify the 6 V maximum supply voltage suits the target circuit. Compare against the XD6130 series if manual reset functionality is preferred over the automatic watchdog behavior.

Supervisors Part Context

This component belongs to the XD6131 series of voltage detectors from Torex Semiconductor. The series is characterized by high precision CMOS technology and includes integrated watchdog timers. It is distinct from the XD6130 series, which typically offers manual reset options. The 'Q' suffix indicates automotive-grade qualification under AEC-Q100 standards.

Supervisors FAQ

Does the XD6131B301MR-Q include a manual reset function?

No, the XD6131 series does not feature a manual reset pin; it relies on the watchdog timer and voltage detection for reset generation.

What is the purpose of the battery backup switch in this device?

The battery backup switch allows the internal logic state to be maintained when the main supply voltage drops below the operating level.
