Maxim Integrated MAX6320PUK29DY+T Microprocessor Supervisory Circuit

The MAX6320PUK29DY+T is a highly reliable microprocessor (μP) supervisory circuit designed and manufactured by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This compact and efficient device is engineered to monitor power supplies in μP and digital systems, providing a significant layer of protection against system failures due to unstable or failing power conditions.

This supervisory circuit is particularly designed to maintain system integrity through various features. One of its primary functions is to assert a reset signal to the μP whenever the VCC supply voltage falls below its preset threshold, ensuring that the μP restarts in a known state during power-up, power-down, or brownout conditions. The reset signal is maintained for a minimum of 140ms after VCC has risen above the reset threshold level, providing ample time for the system to stabilize.

The MAX6320PUK29DY+T operates over a wide voltage range and has a low supply current requirement, which makes it suitable for use in portable and low-power applications. The device comes in a compact 5-pin SOT-23 package, which is ideal for space-constrained applications.

Key features of the MAX6320PUK29DY+T include:

• Factory-trimmed VCC reset threshold for high accuracy
• Low, 1.2μA supply current, which enhances battery life in portable systems
• Guaranteed reset valid to VCC = 1V, ensuring reliable operation during low voltage conditions
• Immunity to short VCC transients, preventing false resets and system disturbances
• 140ms min reset pulse width, providing a stable reset signal for the μP
• Available in a small, 5-pin SOT-23 package, perfect for use in space-constrained designs

The MAX6320PUK29DY+T is ideal for a wide array of applications, including embedded systems, computers, controllers, intelligent instruments, and portable consumer electronics. Its robust design ensures that it can maintain system stability and prevent data corruption during adverse power supply conditions. With Maxim Integrated's reputation for quality and reliability, this supervisory circuit is an excellent choice for designers looking to enhance the operational safety and longevity of their digital systems.
