XC6121F516ER-G

Supervisors Overview

The XC6121F516ER-G is a voltage detector with watchdog function and ON/OFF control manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 2V to 6V. The device features a fixed detection voltage of 1.6V, ensuring precise monitoring of power supply levels. It integrates a watchdog timer to reset the system upon timeout events and includes an output control pin for managing external circuits. The component is housed in a compact 6-pin USP package, suitable for space-constrained applications requiring reliable supervision.

Supervisors Feature Summary

• Integrates voltage detection with watchdog timer functionality
• Includes ON/OFF control output for external circuit management
• Fixed detection voltage ensures consistent threshold monitoring
• Compact surface-mount packaging for efficient board layout

Supervisors Applications

• Portable electronic devices requiring power supervision
• Industrial equipment needing watchdog protection
• Consumer electronics with strict voltage monitoring requirements

Supervisors Procurement Notes

Verify the specific suffix ER-G confirms the 6-USP package and RoHS compliance status. Confirm the detection voltage matches the required 1.6V threshold for your application. Ensure the operating temperature range aligns with your environmental specifications. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a minimal footprint. The fixed 1.6V detection voltage suits low-voltage logic systems. Consider the ON/OFF control feature if active load switching is needed during fault conditions. Verify that the input voltage range covers your system's operational limits without exceeding maximum ratings.

Supervisors Part Context

This part belongs to the XC6121 series of voltage detectors from Torex Semiconductor. The series offers various detection voltages and package options. The F516 variant specifically denotes the 1.6V detection threshold. The ER-G suffix indicates the specific tape-and-reel packaging and lead-free composition. This series is designed for general-purpose power management in portable and industrial applications.

Supervisors Replacement Considerations

Check for XC6121 variants with different detection voltages if 1.6V is not suitable. Verify pinout compatibility with other XC6121 models before substitution. Ensure equivalent watchdog timing characteristics are available in alternative parts. Confirm package dimensions match existing PCB footprints for direct replacement.
