XC6121E747ER-G

Supervisors Overview

The XC6121E747ER-G is a voltage detector supervisor IC manufactured by Torex Semiconductor Ltd. It operates within an input voltage range of 0.8V to 6.0V and features a fixed output threshold of 7.4V, indicated by the '74' in the model number (representing 7.40V). The device provides a reset signal via an open-drain or open-collector output pin, suitable for interfacing with digital logic circuits. It is housed in a compact 6-pin USPC package measuring 1.8mm x 2.0mm, designed for space-constrained applications requiring reliable power monitoring.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed detection threshold
• Features open-drain/open-collector output for flexible logic interfacing
• Compact surface-mount packaging for space-efficient designs

Supervisors Applications

• Microprocessor system reset circuits
• Battery-powered device voltage supervision
• Industrial equipment power monitoring

Supervisors Procurement Notes

Verify the specific suffix 'ER-G' matches the required package type (USPC-6) and lead-free status. Confirm the threshold voltage designation '74' corresponds to the exact 7.4V requirement for your application. Check current availability as stock levels may vary. Ensure compatibility with your system's operating voltage range before procurement.

Supervisors Selection Notes

Select this component when a fixed high-voltage threshold near 7.4V is required for system supervision. Consider the open-drain output capability if level shifting or wired-OR configurations are needed. Evaluate the USPC-6 package size against board space constraints. Compare quiescent current specifications if low-power operation is critical for battery life.

Supervisors Part Context

This part belongs to the XC6121 series of voltage detectors from Torex Semiconductor. The series offers various threshold voltages and output types. The 'E' typically denotes a specific output configuration variant, while '74' specifies the 7.4V threshold. The 'ER-G' indicates the tape-and-reel packaging and environmental compliance. This series is widely used in consumer electronics and industrial control systems.

Supervisors Replacement Considerations

Direct substitutes must match the 7.4V threshold, open-drain output, and USPC-6 package. Verify equivalent supply voltage ranges and response times. Cross-reference manufacturer-specific pinouts to ensure compatibility. Generic LDOs or different supervisor families may not provide the same threshold precision or output structure.
