Maxim Integrated MAX6320PUK29CY-T Microprocessor Supervisory Circuit

The MAX6320PUK29CY-T is a precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability and accuracy required for controlling power functions and reset operations in electronic devices. This supervisory IC is particularly suitable for applications that demand high accuracy and low power consumption.

With a factory-trimmed reset threshold voltage of 2.925V, the MAX6320PUK29CY-T ensures that systems operate within their specified voltage range, protecting them from unpredictable behavior that can occur due to power supply fluctuations. In the event of a power failure or brownout condition, this supervisory circuit generates a reset signal to the µP, thereby resetting the system back to a known state and preventing software execution errors.

The MAX6320PUK29CY-T comes in a compact SOT-23 package, making it an excellent choice for space-constrained applications. The device features a low supply current of only 1µA, which is ideal for portable and battery-powered equipment where power efficiency is critical. The active-low reset output remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold, providing ample time for the system to stabilize before resuming operation.

Key features of the MAX6320PUK29CY-T include:

• Factory-trimmed V_CC reset threshold voltage: 2.925V
• Extended reset timeout: 140ms min
• Low supply current: 1µA
• Wide operating temperature range: -40°C to +85°C
• Compact SOT-23 packaging

This supervisory circuit is an essential component for managing power-on reset functions in microcontrollers, computers, embedded systems, and other digital applications that require precise voltage monitoring. By integrating the MAX6320PUK29CY-T into your design, you can enhance system reliability and performance, ensuring your applications run smoothly even in the face of power supply uncertainties.

Maxim Integrated's commitment to quality and reliability is evident in the MAX6320PUK29CY-T, making it a top choice for designers looking to implement robust power monitoring solutions in their electronic systems.
