Microchip MIC842NYC5-TR: 6V Nanopower Voltage Supervisor with Push-Pull Output

In the world of electronic systems, ensuring stable and reliable operation is paramount. Voltage supervisors, often referred to as voltage monitors or reset ICs, play a critical role in this domain by monitoring power supply rails and generating a reset signal to a microcontroller or processor during power-up, power-down, or brown-out conditions. The Microchip MIC842NYC5-TR stands out as a specialized component designed for applications where both precision and ultra-low power consumption are non-negotiable requirements.

This voltage supervisor is engineered to monitor voltages up to 6V, making it suitable for a broad range of systems powered by 3.3V, 5V, or even unregulated battery sources. Its core functionality is to assert a reset signal whenever the supply voltage drops below a predefined factory-set threshold. This ensures that the connected digital circuitry remains in a known safe state, preventing erratic behavior or data corruption that can occur from operating outside specified voltage tolerances.

A defining characteristic of the MIC842NYC5-TR is its nanopower operation. It consumes an exceptionally low quiescent current, typically in the range of a few hundred nanoamperes. This minuscule power draw is a crucial advantage for battery-powered and portable devices, such as IoT sensors, medical implants, wearable technology, and handheld instruments, where maximizing battery life is the primary design goal. Every microamp saved directly translates into extended operational time between charges or battery replacements.

Furthermore, this IC features a push-pull (PMOS) output stage. Unlike open-drain outputs, which require an external pull-up resistor to function, a push-pull output can actively drive the reset line both high and low. This architecture provides a strong, clean digital signal without any external components, simplifying board design, saving space, and reducing the bill of materials (BOM). It also allows for faster rise times on the output signal, which can be critical for ensuring timing requirements are met in high-speed systems.

Housed in a compact 5-pin SOT-23 package, the MIC842NYC5-TR offers a robust and space-efficient solution for modern, miniaturized PCB designs. Its high factory-set accuracy ensures reliable monitoring, providing designers with confidence in their system's integrity.

ICGOODFIND: The Microchip MIC842NYC5-TR is an optimal choice for designers seeking a high-performance, ultra-low-power voltage supervisor. Its combination of 6V monitoring capability, nanopower consumption, and a convenient push-pull output makes it exceptionally well-suited for power-sensitive portable and battery-operated applications, ensuring reliable system operation and longevity.
