ILC5061M46X

Supervisors Overview

The ILC5061M46X is a CMOS voltage monitoring circuit manufactured by Fairchild Semiconductor, designed for power supply supervision in microprocessor applications. It features a fixed detection threshold of 4.6V with A-grade precision of ±1%. The device operates within an input voltage range of 2.6V to 5.5V and draws a typical quiescent current of only 1µA. It provides an active-low push-pull output capable of sinking over 2mA. The component is housed in a compact SOT-23 package and includes built-in hysteresis equivalent to 5% of the detection voltage to prevent output oscillation during threshold transitions.

Supervisors Feature Summary

• Fixed 4.6V detection threshold with high accuracy
• Ultra-low power consumption suitable for battery systems
• Active-low push-pull output stage
• Built-in hysteresis for noise immunity

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered system supervision
• Portable electronic devices
• Embedded controller power management

Supervisors Procurement Notes

Verify the specific suffix 'M46X' to confirm the 4.6V threshold variant, as this series offers multiple voltage options. Ensure the sourcing channel provides original Fairchild Semiconductor documentation to validate the ±1% A-grade accuracy specification. Confirm the SOT-23 package type matches the design footprint requirements before integration.

Supervisors Selection Notes

Select this component when a precise 4.6V trip point is required for system supervision. The low quiescent current makes it ideal for energy-constrained designs compared to standard regulators. Verify that the 2mA sink capability meets the load requirements of the downstream reset pin. Consider the operating temperature range if deployed in extreme environments.

Supervisors Part Context
