Maxim Integrated MAX6412UK46-T Microprocessor Reset Circuit

The MAX6412UK46-T is a compact, highly reliable microprocessor (μP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides a crucial function by ensuring that the μP and its peripherals are reset properly during power-up, power-down, and brown-out conditions. This particular model is available in a small SOT23-5 package, making it an ideal choice for space-constrained applications.

One of the standout features of the MAX6412UK46-T is its precision factory-set reset threshold voltage. This device triggers a reset when the V_CC supply voltage falls below 4.6V, ensuring that the connected microprocessor is reset in a timely manner to prevent any malfunction due to inadequate power supply. The reset output remains asserted for a minimum reset timeout period after V_CC rises above the reset threshold, providing ample time for the system to stabilize.

The MAX6412UK46-T is characterized by its low power consumption, consuming only 1.2μA of supply current, which is beneficial for battery-powered devices where power efficiency is crucial. Additionally, it operates over a wide supply voltage range from 1.2V to 5.5V, making it versatile for various applications, including portable devices, embedded systems, and IoT devices.

Another advantageous feature of this supervisory circuit is its immunity to short V_CC transients, which enhances the stability of the system it is protecting. The device also includes a manual reset input, allowing for a system reset to be initiated externally if necessary.

For designers and engineers looking for a robust and reliable solution to safeguard their digital systems, the MAX6412UK46-T from Maxim Integrated is an excellent choice. Its combination of precision voltage monitoring, low power consumption, and small form factor makes it a go-to component for maintaining the integrity and stability of microprocessor-based systems.

Whether you're working on consumer electronics, industrial controls, or automotive systems, the MAX6412UK46-T offers the performance and reliability that modern digital applications demand.
