XC6121D543ER-G

Supervisors Overview

The XC6121D543ER-G is a voltage detector manufactured by Torex Semiconductor, designed to monitor supply voltages and generate reset signals. It operates within an input voltage range of 0.8V to 6V. The device features a fixed output threshold of 5.43V with a typical accuracy of ±1%. It includes an internal delay time circuit to prevent false triggering during power-up or noise events. The component supports open-drain or push-pull output configurations and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors supply voltage levels to ensure system stability
• Provides precise threshold detection with low hysteresis
• Includes built-in delay timer for noise immunity
• Supports multiple output logic types for interface flexibility

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered equipment monitoring
• Portable electronic devices
• Industrial control systems

Supervisors Procurement Notes

Verify the specific output configuration (open-drain vs. push-pull) and package type against the official datasheet before ordering. Confirm that the 5.43V threshold aligns with the target system's reset requirements. Ensure compatibility with the operating temperature range specified for the application environment.

Supervisors Selection Notes

Select this component when a fixed high-voltage threshold near 5.4V is required for system supervision. Consider the internal delay characteristics if fast response times are not critical but noise immunity is a priority. Evaluate the output drive capability to ensure it meets the load requirements of the connected microcontroller or logic gate without external pull-up resistors if using push-pull output.

Supervisors Part Context

This part belongs to the XC6121 series of voltage detectors from Torex Semiconductor. The series offers various threshold voltages and output configurations to suit different monitoring needs. The XC6121 family is known for low current consumption and high accuracy, making it suitable for battery-operated applications where power efficiency and reliable voltage supervision are essential.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the XC6121 series with different threshold voltages if the 5.43V level is unsuitable. Verify functional equivalence with other voltage detectors offering similar threshold accuracy and delay characteristics. Ensure any substitute component matches the package outline and electrical specifications exactly.
