Maxim Integrated MAX6316LUK29CY Microprocessor Reset Circuit

The Maxim Integrated MAX6316LUK29CY is a highly precise and reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected events. This essential component is engineered to monitor the power supply voltage in digital systems and provide a reset signal to the host processor when necessary, ensuring a proper system boot-up every time.

With a factory-trimmed reset threshold voltage set at 2.9V, the MAX6316LUK29CY is well-suited for 3.3V-powered systems, providing a robust defense against power supply transients and brown-out conditions. The device features an active-low, push-pull reset output, which remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold. This ensures a sufficient reset signal duration for most µP and DSP applications.

The compact SOT-23 package makes the MAX6316LUK29CY an ideal choice for space-constrained applications, while its low supply current of only 1.6µA (typical) makes it an energy-efficient option for portable and battery-operated devices. The device's high precision voltage monitoring and reset capabilities make it an indispensable component in a wide range of applications, including computers, controllers, intelligent instruments, and critical system monitoring devices.

Key features of the MAX6316LUK29CY include:

• Factory-set reset threshold voltage: 2.9V
• Low supply current: 1.6µA (typ.)
• Reset signal valid down to V_CC = 1V
• Minimum reset pulse duration: 140ms
• Active-low, push-pull reset output
• Compact SOT-23 package
• Immune to short V_CC transients

Maxim Integrated's commitment to quality and reliability is evident in the MAX6316LUK29CY, which is designed to meet the stringent requirements of modern electronic systems. By integrating this reset circuit into your design, you can enhance system stability and reliability, ensuring that your application operates at its best even under adverse conditions.
