Product Overview: MIC2774L-46YM5-TR from Microchip Technology

The MIC2774L-46YM5-TR is a high-performance, low-power microprocessor supervisory circuit manufactured by Microchip Technology, designed to monitor power supplies in digital systems. It provides a crucial function by ensuring that the system's microprocessor and other digital components operate within specified power supply parameters, thus enhancing system reliability and preventing potential damage due to power anomalies.

This supervisory circuit is particularly suitable for battery-powered devices due to its low power consumption. It features a precision voltage monitor with programmable delay, which allows designers to set the appropriate power-on reset (POR) delay and ensure the system has stabilized before the microprocessor starts to execute code.

Key Features:

• Reset Threshold Voltage: The MIC2774L-46YM5-TR has a preset threshold voltage of 4.63V, which is ideal for systems that operate at 5V supply levels.
• Low Quiescent Current: It boasts a low quiescent current of typically 3.5 µA, making it an energy-efficient choice for portable and battery-operated applications.
• Manual Reset Input: A manual reset input is provided, allowing for a system reset to be initiated by external hardware or software, offering an additional layer of system control.
• Programmable Reset Delay: The reset delay time can be programmed by an external capacitor, offering flexibility to match the needs of specific applications.
• Active Low Reset Output: The device features an active low reset output, which remains asserted for the reset delay period after the monitored voltage exceeds the reset threshold or after a manual reset has been initiated.
• Small Package: Packaged in a compact SOT-23-5, the MIC2774L-46YM5-TR is suitable for space-constrained applications.

With its precision voltage monitoring and programmable features, the MIC2774L-46YM5-TR is a versatile component that can be used in a wide range of applications, including PDAs, portable instrumentation, embedded controllers, and intelligent battery packs. Its robust design ensures that it can maintain system integrity by providing a reliable reset signal to the processor, thereby preventing the execution of erroneous operations due to power supply irregularities.

As a product from Microchip Technology, a leading provider of microcontroller and analog semiconductors, the MIC2774L-46YM5-TR comes with the assurance of high-quality standards and excellent technical support.
