Maxim Integrated MAX6358TWUT+T Microprocessor Reset Circuit

The Maxim Integrated MAX6358TWUT+T is a highly reliable, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems and provide a reset signal to the host processor when necessary. This ensures that the µP and its associated circuitry reset to a known state during power-up, power-down, or brown-out conditions.

This device operates with a supply voltage range from 1.2V to 5.5V, making it versatile for use in a wide array of applications, from portable devices to complex digital systems. The MAX6358TWUT+T comes in a compact, 6-pin SOT-23 package, which is ideal for space-constrained applications. The small footprint of the device is an advantage for designers looking to integrate reset circuits without compromising on board space.

One of the key features of the MAX6358TWUT+T is its factory-trimmed reset threshold voltage. This precision ensures that the reset activation is reliable and consistent, which is critical for maintaining system integrity. The device also offers a reset timeout period of 140ms (min), which provides enough time for the system to stabilize before normal operation resumes. The reset output is active-low and is guaranteed to be in the correct state for V_CC down to 1.1V.

The MAX6358TWUT+T also includes a manual reset input, which allows for an external signal to trigger a system reset. This can be useful for system maintenance, debugging, or when user-initiated resets are required. Additionally, the device is designed with low supply current characteristics, typically 1.5µA at 1.8V, which contributes to the overall power efficiency of the system it is monitoring.

Maxim Integrated's commitment to quality and reliability is evident in the MAX6358TWUT+T, with its robust design and built-in electrostatic discharge (ESD) protection. This device is an excellent choice for engineers who require a dependable reset circuit for their digital systems, ensuring that their products operate smoothly and reliably under various conditions.

Overall, the MAX6358TWUT+T is a testament to Maxim Integrated's expertise in creating compact, efficient, and reliable integrated circuits that meet the stringent demands of modern electronic systems.
