Microchip Technology MIC811LUY-TR Voltage Supervisor

The MIC811LUY-TR from Microchip Technology is a highly reliable voltage supervisor device designed to monitor power supplies in microprocessor and digital systems, providing a significant layer of protection against low voltage conditions. This compact component is essential in applications where maintaining the correct operation voltage is critical for system stability and data integrity.

With its precision monitoring capability, the MIC811LUY-TR ensures that the system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The device features an active-low reset output, with the reset signal being asserted when the monitored voltage drops below a predefined threshold. The reset signal remains asserted for a period after the voltage rises above the reset threshold, ensuring the system has adequate time to stabilize.

The MIC811LUY-TR is offered in a small 3-pin SOT-23 package, making it ideal for space-constrained applications. It supports a threshold voltage of 4.63V, which is suitable for 5V-operated systems. The device's low supply current of 9µA (typical) makes it an energy-efficient choice for portable and battery-operated electronics.

Key features of the MIC811LUY-TR include:

• Supply voltage monitoring at 4.63V threshold
• Low power consumption with 9µA typical supply current
• Active-low reset output
• Guaranteed reset valid to VCC = 1V
• Immunity to short VCC transients
• Fast response time
• Built-in manual reset capability
• Operating temperature range from -40°C to +85°C
• RoHS compliant and lead-free

This voltage supervisor is designed for a wide array of applications including computers, controllers, intelligent instruments, portable/battery-powered products, and other digital systems that require voltage monitoring for safe operation. The MIC811LUY-TR's combination of features ensures that it is a go-to solution for designers looking to enhance the reliability and performance of their systems.

Microchip Technology's commitment to quality and reliability is evident in the MIC811LUY-TR voltage supervisor, providing designers with the confidence that their systems are protected against unexpected power anomalies.
