ILC5061AM27X

Supervisors Overview

The ILC5061AM27X is a precision power supply reset monitor manufactured by Fairchild Semiconductor, now part of onsemi. It operates within a supply voltage range of 1.8V to 5.5V and features an active-low push-pull output. The device provides a fixed detection threshold of 2.7V with A-grade accuracy of ±1%. It incorporates built-in hysteresis equal to 5% of the detection voltage to prevent false triggering during slow input transitions. The component draws only 1µA of quiescent current while capable of sinking over 2mA of output current.

Supervisors Feature Summary

• All-CMOS design optimized for low power consumption and high accuracy in voltage monitoring applications
• Active-low push-pull output stage providing robust drive capability for microprocessor reset lines
• Built-in hysteresis ensures stable operation and prevents output oscillation during slow power supply ramp-up

Supervisors Applications

• Microprocessor supervisory circuits requiring precise voltage tracking
• Battery-powered portable devices needing extended operational life through ultra-low quiescent current
• Embedded systems utilizing standard CMOS logic families for reset signal generation

Supervisors Procurement Notes

Verify the manufacturer status as Fairchild Semiconductor products are integrated into onsemi. Confirm the specific suffix 'AM27X' denotes the A-grade ±1% accuracy and 2.7V threshold variant. Check for obsolescence notices or lifecycle changes associated with the legacy Fairchild portfolio. Ensure compatibility with the target system's voltage levels and package requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 2.7V threshold with high precision is required for system supervision. The A-grade accuracy makes it suitable for sensitive digital logic that cannot tolerate wide voltage variations. Consider the SOT-23 package size for space-constrained designs. Evaluate the need for hysteresis to handle noisy power rails without external components.

Supervisors Part Context

This part belongs to the ILC5061 series of voltage supervisors. It shares architectural similarities with other members like the ILC5062 but differs in specific threshold voltages and package options. The series is designed to replace older discrete resistor divider solutions with a single integrated IC offering superior accuracy and lower standby current.

Supervisors Replacement Considerations

Direct substitutes include other ILC5061 variants with different thresholds or grades. Cross-reference with similar supervisor ICs from other manufacturers ensuring matching voltage thresholds, output polarity, and package dimensions. Verify electrical characteristics such as quiescent current and sink capability to ensure functional equivalence.
