Maxim Integrated MAX6316LUK29BY+T Microprocessor Reset Circuits

The MAX6316LUK29BY+T is a highly reliable microprocessor (µP) supervisory circuit that provides a compact and efficient solution for monitoring power supplies in µP and digital systems. Manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering, this component ensures that your system maintains its integrity during power-up, operation, and power-down sequences.

This supervisory IC is designed to maintain system integrity by monitoring the power supply voltage. It features a factory-trimmed reset threshold level of 2.93V, which is suitable for 3V-powered circuits. When the VCC supply voltage falls below this threshold, the reset output is driven active, thus signaling the connected µP to reset, preventing code execution errors, and ensuring proper system reboot once the supply voltage returns to an acceptable level.

One of the key features of the MAX6316LUK29BY+T is its low supply current of 1.5µA (typical), which makes it an energy-efficient choice for battery-powered applications. The device comes in a small, 5-pin SOT-23 package, which is ideal for space-constrained applications.

Additional features of this reset circuit include a debounced manual reset input, which allows for a manual system reset. It also has an active-low reset output, which is guaranteed to be in the correct state for VCC down to 1V, ensuring reliable operation even during low voltage conditions. The reset signal from the device remains active for a minimum of 140ms after VCC has risen above the reset threshold, providing ample time for the system to stabilize before coming out of reset.

The MAX6316LUK29BY+T is fully specified over the temperature range of -40°C to +85°C, allowing for use in environments with varying temperature conditions. With its precision voltage monitoring and low power consumption, this supervisory circuit is an excellent choice for portable devices, computers, controllers, and other critical µP-based systems that require a high degree of reliability.

By integrating the MAX6316LUK29BY+T into your design, you can ensure that your system will respond appropriately to power disturbances, enhancing the overall stability and performance of your application.
