Microchip Technology MIC2774N-46BM5-TR

The MIC2774N-46BM5-TR from Microchip Technology is a high-performance, dual-voltage supervisor integrated circuit designed to monitor power supplies in digital systems. It ensures that the system microprocessor or other critical components operate reliably by providing a reset signal during power-up, power-down, and brown-out conditions. The device is ideal for battery-powered electronics, portable devices, and other applications where power supply stability is crucial.

This supervisor IC is equipped with two voltage detectors, each with a fixed threshold, ensuring that both supplies are monitored for under-voltage conditions. The MIC2774N-46BM5-TR features an active-low reset output, which is asserted when either of the input voltages falls below the respective threshold levels. The reset signal remains asserted for a period after both voltages rise above the thresholds, providing a stable reset to the system.

Key features of the MIC2774N-46BM5-TR include:

• Dual Voltage Monitoring: Allows simultaneous supervision of two power supplies, enhancing system reliability.
• Fixed Threshold Levels: Precision voltage thresholds are factory set, eliminating the need for external resistors and simplifying design.
• Low Power Consumption: With its low operating current, the device is suitable for power-sensitive applications.
• Manual Reset Input: Provides the ability to trigger a system reset manually, offering additional control to the user or system.
• Compact Package: The SOT-23-5 package is space-efficient, making it ideal for use in portable and space-constrained applications.

The MIC2774N-46BM5-TR operates over a wide temperature range, making it suitable for a variety of environments. Its robust design ensures reliable operation even under adverse conditions. The device is also available in tape and reel packaging (denoted by the 'TR' suffix), which is convenient for automated manufacturing processes.

Whether used in microprocessor systems, data storage devices, or portable consumer electronics, the MIC2774N-46BM5-TR is a versatile solution that provides critical protection against power supply anomalies, ensuring stable and reliable operation of the end product.
