Maxim Integrated MAX6747KA26+T Microprocessor Supervisory Circuits

The MAX6747KA26+T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring. This supervisory circuit is ideal for use in a wide range of applications including computers, controllers, portable/battery-powered equipment, and intelligent instruments.

One of the key features of the MAX6747KA26+T is its ability to assert a reset signal whenever the VCC supply voltage falls below a preset threshold, ensuring that the µP starts up in a known state. The reset output remains asserted for a period after VCC has risen above the reset threshold, providing enough time for the system to stabilize before the processor begins operation. This minimizes the risk of improper system functioning due to insufficient power supply at startup.

The device operates over a wide voltage range from 1.6V to 5V, making it versatile for various applications. The MAX6747KA26+T comes in a compact SOT-23 package, which is suitable for space-constrained applications. It also features a low supply current of 8.2µA, which is beneficial for power-sensitive designs.

Additionally, the MAX6747KA26+T offers a manual reset input that allows for a system reset to be triggered with an external signal, providing an extra layer of control. It is also equipped with a watchdog timer that forces the system into a reset state if the µP fails to provide a periodic signal, indicating that the system is functioning correctly.

For designers looking for a robust and reliable solution to ensure system integrity during power-up, brownout conditions, and operation, the MAX6747KA26+T from Maxim Integrated is an excellent choice. Its combination of features, compact size, and ease of use make it a valuable component in maintaining system stability and performance.

Overall, the MAX6747KA26+T is a testament to Maxim Integrated's commitment to providing advanced integrated circuits that meet the stringent requirements of modern electronic systems.
