ON Semiconductor CAT872-30ULGT3 Voltage Supervisor IC

The CAT872-30ULGT3 from ON Semiconductor is a precision voltage supervisor integrated circuit (IC) designed to keep microprocessors and digital systems operating within their proper voltage ranges. This robust IC is essential for applications that require reliable system operation and protection against unpredictable voltage fluctuations.

The device features a fixed threshold voltage of 3.0V, making it an ideal choice for monitoring 3.3V power supply lines. It ensures that systems are reset to a known state after power-up or during a brown-out condition. The CAT872-30ULGT3 helps to prevent system errors and data corruption by providing an active-low reset signal when the monitored voltage drops below the threshold level.

This voltage supervisor comes in a compact SOT-23 package, which is perfect for space-constrained applications. It consumes a low supply current, making it suitable for battery-operated devices where power efficiency is critical. The device also features a built-in delay time which allows the system to stabilize before the reset signal is deasserted, ensuring reliable system restarts.

• Key Features:
• Precision monitoring of 3.0V power supplies
• Active-low reset output
• Low supply current for power-sensitive applications
• Built-in delay time for system stabilization
• Compact SOT-23 package for space-saving designs

The CAT872-30ULGT3 is a must-have for engineers and designers looking for a simple yet effective solution to enhance the reliability of their digital systems. It is widely used in microprocessor-based systems, portable electronics, and any application where voltage integrity is paramount. With ON Semiconductor's commitment to quality and performance, this voltage supervisor IC stands out as a reliable component for safeguarding electronic systems against the perils of inadequate power supply levels.
