XC6123A535MR-G

Supervisors Overview

The XC6123A535MR-G is a single-channel voltage supervisor IC manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 0.7V to 6V and features a fixed detection threshold of 3.5V. The device utilizes an SOT-25-5 package and provides an open-drain or open-collector reset output. It includes a built-in watchdog timer function with a timeout period of approximately 1.4 seconds, ensuring system reliability through continuous monitoring of the power supply voltage.

Supervisors Feature Summary

• Integrates a watchdog timer circuit for automated system recovery from software faults
• Provides a dedicated reset signal output when input voltage drops below the set threshold
• Operates effectively across a wide input voltage range suitable for various battery-powered applications

Supervisors Applications

• Portable electronic devices requiring reliable power management
• Embedded systems needing watchdog functionality for fault protection
• Battery-operated equipment where low standby current is critical

Supervisors Procurement Notes

Verify the specific suffix codes against official Torex documentation to confirm pinout compatibility and functional variations. Ensure the sourcing channel provides genuine components with traceable manufacturing dates. Cross-reference the part number with the latest datasheet revisions to account for any packaging or specification updates prior to final procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 3.5V threshold is required alongside integrated watchdog capabilities. Consider the SOT-25-5 footprint constraints and the open-drain output drive requirements. Evaluate the operating temperature range and static current consumption against the specific application's power budget and environmental conditions.

Supervisors Part Context

This supervisor belongs to the XC6123 series, designed for compact power management solutions. It complements other Torex PMIC offerings by providing essential monitoring functions in a minimal footprint. The series targets applications demanding high reliability and space efficiency in consumer and industrial electronics.

Supervisors Replacement Considerations

Check for XC6123 series variants with different threshold voltages if the 3.5V level is unsuitable. Verify pin-to-pin compatibility with alternative supervisors offering similar watchdog features before substitution.
