Maxim Integrated MAX6355LSEUT Microprocessor Supervisory Circuit

The MAX6355LSEUT from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of protection for your sensitive electronic equipment. This supervisory circuit ensures that your system operates within the safe voltage thresholds, and it initiates a reset to the microprocessor during power-up, power-down, or brown-out conditions.

One of the key features of the MAX6355LSEUT is its ability to provide a precise, factory-trimmed reset threshold voltage. This ensures that the device can maintain system integrity by resetting the µP in the event of an undervoltage condition. The reset output remains asserted for a minimum reset timeout period after VCC has risen above the reset threshold level, providing a guaranteed reset duration for the µP to recover and initialize properly.

The MAX6355LSEUT comes in a compact, surface-mount SOT-23 package, making it ideal for space-constrained applications. Its low supply current of 1.6µA (typical) ensures minimal power consumption, which is critical for battery-operated and portable devices. The device operates over a wide supply voltage range, typically from 1.2V to 5.5V, which allows for flexibility in various system designs.

Additional features of the MAX6355LSEUT include a debounced manual reset input, which allows for a manual system reset. This can be a valuable feature for service personnel or for system testing purposes. The device also offers an active-low push-pull reset output, which provides a direct interface to the reset pin of the µP without the need for external components.

In summary, the Maxim Integrated MAX6355LSEUT is a robust and versatile supervisory circuit that provides essential protection for microprocessor systems. With its precise voltage monitoring, low power consumption, and compact form factor, it is an excellent choice for a wide range of applications, from portable devices to complex digital systems.
