Introducing the MAX810R-2.63 from Maxim Integrated

The MAX810R-2.63 is a precision microprocessor (µP) supervisory circuit tailored to monitor power supplies in digital systems. Designed by Maxim Integrated, a trusted leader in the development of analog and mixed-signal products, this device ensures reliable system operation through its reset and monitoring functions. It is an essential component for managing system integrity in a wide array of applications, from computers and controllers to intelligent instruments.

One of the key features of the MAX810R-2.63 is its ability to assert a reset signal whenever the VCC supply voltage drops below a preset threshold of 2.63 Volts. This reset signal maintains its active state for a minimum of 140ms after VCC has risen above the reset threshold, providing ample time for the system to stabilize. This ensures that the µP and other critical components can initiate with a clean start, reducing the risk of malfunction or data corruption due to power supply inconsistencies.

The device operates over a wide supply voltage range from 1.2V up to 5.5V, which allows it to be used in various low-power and standard voltage applications. The low supply current of just 20µA (typical) makes the MAX810R-2.63 an excellent choice for battery-operated equipment where power conservation is crucial.

The MAX810R-2.63 comes in a compact SOT-23 package, which is ideal for space-constrained applications. It is also characterized for operation over a full automotive temperature range of -40°C to +125°C, ensuring reliable performance in harsh environments.

Additional features include:

• Immunity to short VCC transients
• No external components required
• Debounced manual reset input

Overall, the MAX810R-2.63 supervisory circuit from Maxim Integrated offers a robust and straightforward solution for system power supply monitoring. Its precision monitoring capabilities, low power consumption, and compact form factor make it an indispensable component for ensuring the stability and reliability of a wide range of electronic systems.
