Maxim Integrated MAX6316LEUK46BY Microprocessor Supervisory Circuit

The MAX6316LEUK46BY is a sophisticated microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. Manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering, this component provides excellent circuit reliability and low-cost system monitoring solutions with its compact and feature-rich design.

This supervisory circuit is specifically tailored to maintain system integrity through monitoring the power supply voltage. It ensures that the µP boots up in a predictable state by providing a reset signal to the µP during power-up, power-down, and brownout conditions. The reset output remains operational with VCC as low as 1V, and the device features an active-low RESET output which asserts a reset signal whenever the VCC supply voltage falls below the factory-set reset threshold. The reset signal remains asserted for a minimum reset timeout period after VCC rises above the reset threshold to ensure the system has stabilized before the processor starts operating.

The MAX6316LEUK46BY comes with a preset reset threshold voltage of 4.63V, which is suitable for 5V-powered systems. Its low supply current of only 1.6µA (typical) makes it an energy-efficient choice for portable and battery-operated applications. The device is offered in a compact SOT-23 package, making it ideal for space-constrained applications.

Key features of the MAX6316LEUK46BY include:

• Factory-set reset threshold suitable for 5V systems
• Low 1.6µA supply current
• Guaranteed reset valid to VCC = 1V
• Reset timeout period of 140ms (min)
• Immune to short VCC transients
• Compact SOT-23 package

With its precision monitoring and low power consumption, the MAX6316LEUK46BY is an excellent choice for managing power supplies in critical systems where reliability is paramount. It is widely used in applications such as computers, controllers, intelligent instruments, and portable/battery-powered equipment.

Maxim Integrated's commitment to quality ensures that the MAX6316LEUK46BY meets the stringent requirements of modern electronic systems, offering both reliability and peace of mind for designers and engineers.
