XC6121D549ER-G

Supervisors Overview

The XC6121D549ER-G is a voltage detector manufactured by Torex Semiconductor Ltd. It features an ultra-low current consumption of 0.3 µA (typical) at VDD = 2.0 V, ensuring minimal power drain in standby modes. The device provides a fixed output delay time of 20 ms (typical), which helps prevent false triggering due to noise during power-up sequences. It operates within a supply voltage range of 0.7 V to 6.0 V and offers high accuracy for the detection voltage, specified at ±1.0% or ±20 mV (whichever is greater). The component is housed in a compact SOT-89-3 package, suitable for space-constrained portable applications.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify the specific suffix 'ER-G' confirms the tape-and-reel packaging format and lead-free compliance status as per the manufacturer's latest documentation. Ensure the order quantity matches the reel specifications provided by authorized distributors. Cross-reference the date code and lot number against the datasheet revision history to confirm compatibility with current manufacturing standards. Always request the official datasheet from Torex Semiconductor Ltd for final electrical parameter validation before integration.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical for battery-operated applications. The fixed delay feature makes it suitable for systems where noise immunity during power-up is essential without requiring external capacitors. Verify that the required detection voltage aligns with the available fixed options in the XC6121 series. Consider the SOT-89-3 package size if board space is limited compared to smaller alternatives like X2OR or X2ON packages.

Supervisors Part Context

The XC6121 series represents Torex's line of high-accuracy voltage detectors designed for low-power applications. This specific model integrates a precision reference voltage source and a comparator to monitor supply levels. It is part of a broader family offering various detection voltages and package options, catering to diverse consumer electronics and industrial control needs while maintaining consistent performance characteristics across the series.

Supervisors Replacement Considerations

Direct replacements must match the 5.49V detection threshold and 0.3µA current consumption. Check for equivalent delay times and package compatibility. Verify pinout configurations to ensure direct interchangeability without circuit redesign. Consult Torex Semiconductor Ltd for officially listed compatible parts or updated series revisions.
