Product Overview: MAX934ESE+T by Maxim Integrated

The MAX934ESE+T is a high-precision, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated, a leader in analog and mixed-signal engineering. This component is engineered to monitor power supplies in µP and digital systems, providing a reliable solution for system reset and monitoring functions. It is an ideal choice for portable/battery-powered applications, computers, controllers, and intelligent instruments.

Encased in a 16-pin narrow SO package, the MAX934ESE+T offers four key functions: a reset output during power-up, power-down, and brownout conditions; an independent watchdog timer with a dedicated input; a manual reset input; and a debounced momentary switch input that can be used for a manual reset or as a general-purpose input.

One of the standout features of the MAX934ESE+T is its low power consumption, with a typical supply current of only 12µA, which helps to extend the life of battery-powered devices. The device operates over a wide voltage range of 2.5V to 5.5V, making it versatile for various applications. The reset output is guaranteed to be in the correct state for VCC down to 1V, ensuring reliable operation during power fluctuations.

Furthermore, the MAX934ESE+T provides an adjustable reset timeout period, which can be set by external capacitors, and the watchdog timer features a 1.6-second timeout that is also adjustable with external components. This flexibility allows designers to tailor the supervisory functions to the specific needs of their application.

For added convenience, the MAX934ESE+T features an active-low reset output, which can be configured as push-pull or open-drain, depending on the requirements of the system. The manual reset function is both TTL and CMOS compatible, ensuring easy integration with a wide range of digital systems.

In summary, the MAX934ESE+T from Maxim Integrated is a multifunctional supervisory circuit that offers reliable monitoring and reset capabilities for microprocessor systems. Its low power consumption, wide operating voltage range, and configurable options make it a versatile and essential component for ensuring system stability and performance.
