Maxim Integrated MAX6362LUT26+T Microprocessor Supervisory Circuit

The MAX6362LUT26+T from Maxim Integrated is a highly sophisticated microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a crucial safeguard against low-voltage conditions, which can lead to system errors and data corruption. This component is ideal for use in a variety of applications, including portable devices, computers, controllers, and intelligent instruments where precise voltage monitoring is essential.

Encased in a compact SOT23-6 package, the MAX6362LUT26+T offers a low supply current feature, making it suitable for battery-operated devices. The supervisory circuit operates over a wide voltage range and has a preset threshold voltage of 2.63V, which ensures that the µP is reset to a known state during power-up, power-down, or brownout conditions. Its active-low, push-pull reset output remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring a proper system reset.

One of the key attributes of the MAX6362LUT26+T is its ability to perform a manual reset function. This allows the user to trigger a system reset through an external switch or a software command, providing an additional layer of system control. The manual reset input is debounced, eliminating the possibility of false triggers due to switch bounce or noisy signals.

The device also features a low-power consumption profile, with a typical supply current of only 1.2µA at VCC = 3.3V. This makes it an excellent choice for power-sensitive applications. Furthermore, the MAX6362LUT26+T is specified to operate over the extended -40°C to +85°C temperature range, ensuring reliable performance in various environmental conditions.

With its combination of features, the MAX6362LUT26+T provides robust and reliable voltage monitoring, making it an essential component for maintaining the integrity of microprocessor systems. Maxim Integrated's commitment to quality ensures that this supervisory circuit meets the stringent requirements for critical system applications.
