XC6121F548ER-G

Supervisors Overview

The XC6121F548ER-G is a voltage detector manufactured by Torex Semiconductor, designed for supervisory applications. It operates within a supply voltage range of 1 V to 6 V and features a detection threshold of 5.48 V. The device utilizes an open-drain output configuration and includes a reset delay time of 100 ms. It incorporates a watchdog timer function and supports battery backup switching. The component is available in a 6-USPC (1.8x2) surface-mount package and maintains a low operating current of 12 uA with a static current of 5 uA. It functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring
• Supports battery backup switching functionality
• Features open-drain output for flexible logic interfacing

Supervisors Applications

• Supervisory circuits for portable electronic devices
• Battery voltage monitoring systems
• Microprocessor reset generation in embedded systems

Supervisors Procurement Notes

Verify the specific suffix ER-G corresponds to the required 6-USPC packaging and tape-and-reel delivery format. Confirm that the 5.48 V threshold aligns with the target circuit's trip point requirements. Ensure compatibility with the specified 1 V to 6 V operating voltage range and check for any RoHS compliance documentation if required by the manufacturing process.

Supervisors Selection Notes

Select this component when a precise 5.48 V detection threshold is required for single-input voltage monitoring. Consider the 100 ms reset delay and open-drain output characteristics for timing and interface compatibility. Evaluate the 12 uA operating current against power budget constraints. Verify that the 6-USPC package fits the available PCB footprint and that the -40°C to +85°C temperature range meets environmental specifications.

Supervisors Part Context

This part belongs to the XC6121 series of voltage detectors from Torex Semiconductor. The series is characterized by high-accuracy CMOS technology and laser trimming for precise threshold settings. These devices are designed for low-power applications requiring reliable supervision of single voltage rails in compact surface-mount packages.

Supervisors Replacement Considerations

Cross-reference with other XC6121 variants sharing the same package but different thresholds or delays. Verify functional equivalence regarding watchdog capabilities and backup switch support before substitution.
