XC6124A432MR-G

Supervisors Overview

The XC6124A432MR-G is a voltage monitor supervisory circuit manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and consumes a typical operating current of 12 uA. The device features a fixed threshold voltage of 4.3 V with a reset delay time of 50 ms. It provides an open-drain CMOS output and includes integrated watchdog timer and battery backup switch functions. The component supports power failure detection and is housed in a compact SOT-25-5 package, suitable for surface mount installation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function for system reliability monitoring
• Includes a dedicated battery backup switch capability
• Provides power failure detection functionality
• Features an open-drain CMOS output interface

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems utilizing backup switching
• Industrial control circuits needing watchdog protection
• Embedded systems requiring voltage supervision

Supervisors Procurement Notes

Verify the specific suffix 'A' against official Torex documentation to confirm the exact threshold voltage and feature set, as alphanumeric codes define precise electrical parameters. Confirm the SOT-25-5 package availability and ensure the 12 uA operating current meets system power budgets. Cross-reference the 50 ms reset delay with timing requirements. Validate RoHS compliance status through the manufacturer's datasheet before procurement.

Supervisors Selection Notes

Select this component when a 4.3 V threshold is required for single-input voltage monitoring. The 12 uA operating current makes it suitable for power-sensitive applications compared to higher consumption alternatives. Ensure the design accommodates the open-drain output configuration and utilizes the internal watchdog and backup features if needed. Verify that the 6 V maximum input voltage aligns with the system supply rails.

Supervisors Part Context

This part belongs to the XC6124 series of supervisory circuits from Torex Semiconductor. The series is characterized by low power consumption and integrated safety features like watchdog timers. The XC6124A432MR-G specifically denotes a variant with a 4.3 V threshold and open-drain output, designed for compact surface-mount applications in portable and industrial electronics.

Supervisors Replacement Considerations

Check for XC6124C432MR-G or XC6124E432MR-G variants if different reset delays or output types are acceptable. Verify pin compatibility with the SOT-25-5 package. Ensure substitute parts maintain the 12 uA operating current and 6 V maximum voltage rating.
