Maxim Integrated MAX6734KASVD3 Single-/Dual-/Triple-Voltage µP Supervisory Circuits

The Maxim Integrated MAX6734KASVD3 is a highly reliable microprocessor (µP) supervisory circuit designed to monitor single, dual, or triple voltage systems. It ensures that digital systems maintain their integrity during power-up, operation, and power-down. This device is particularly critical in applications where precise voltage monitoring is crucial for data integrity and system stability.

The MAX6734KASVD3 supervisory circuit features a combination of functionalities that make it a versatile solution for a wide range of applications. One of its key features is the ability to monitor multiple voltages without the need for external resistors, which simplifies design and reduces component count. This device offers factory-set reset threshold voltages, making it suitable for monitoring 3V, 3.3V, and 5V powered systems.

With a low supply current of just 8µA, the MAX6734KASVD3 is an energy-efficient choice for battery-powered and portable devices. It also provides a manual reset input, allowing for a system reset to be triggered by an external signal. This is particularly useful for systems that require user-initiated resets or for systems that need to be reset remotely.

The device features an active-low push-pull reset output, which provides a robust signal to reset the µP. The reset signal remains asserted for a minimum of 140ms after all the monitored voltages have stabilized, ensuring that the system has sufficient time to recover and initialize properly. Additionally, the MAX6734KASVD3 includes an integrated watchdog timer that can be disabled if not required, offering further flexibility in system design.

Available in a compact 8-pin SOT23 package, the MAX6734KASVD3 is designed for space-constrained applications. Its small footprint makes it an ideal choice for portable devices, networking equipment, computers, and any other systems where space is at a premium.

With its combination of features, the Maxim Integrated MAX6734KASVD3 supervisory circuit provides a reliable solution for system voltage monitoring and management, ensuring that electronic systems operate smoothly and without interruption.
