Maxim Integrated MAX6355RWUT Microprocessor Supervisory Circuit

The MAX6355RWUT from Maxim Integrated is a highly reliable and compact microprocessor (μP) supervisory circuit designed to monitor power supplies in μP and digital systems. It provides maximum protection for your system by ensuring that the μP boots up in a predictable state every time. The device is particularly suitable for portable, battery-powered applications due to its low power consumption and small footprint.

This supervisory circuit offers several key features that make it an essential component for system stability. It includes a precision voltage monitor with a factory-set reset threshold voltage, ensuring accurate monitoring of the VCC supply voltage. The reset output is available in both active-low and active-high configurations, providing versatility for different system requirements.

The MAX6355RWUT comes in a tiny, 6-pin SOT-23 package, making it ideal for space-constrained applications. Despite its small size, it offers robust performance with a reset timeout period of 140ms (min), which gives the system adequate time to stabilize before the μP starts its operation. Additionally, the device operates over a wide supply voltage range (from 1.2V to 5.5V), catering to a variety of μP systems and ensuring compatibility with both legacy and modern hardware designs.

One of the critical advantages of the MAX6355RWUT is its low supply current of 1.5μA (typ), which is particularly beneficial for extending battery life in portable devices. The device also features an active-low manual reset input, allowing for a manual system reset, which can be a crucial feature for system maintenance and troubleshooting.

The MAX6355RWUT is designed to be robust and reliable, with built-in immunity to short VCC transients, ensuring that the supervisory circuit will not generate false resets during brief power dips. This stability is paramount in critical applications where consistent operation is a must.

In summary, the Maxim Integrated MAX6355RWUT is a versatile, power-efficient, and reliable solution for microprocessor system management, providing essential monitoring and control to ensure smooth and predictable system operation.
