Maxim Integrated MAX6719UTSFD1+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX6719UTSFD1+T is a highly reliable and versatile microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring and processor supervision.

This compact supervisory IC is ideal for portable and battery-powered applications, thanks to its low power consumption and small footprint. The MAX6719UTSFD1+T is available in a space-saving, 6-pin SOT-23 package, making it suitable for use in space-constrained applications.

Key features of the MAX6719UTSFD1+T include:

• Voltage Monitoring: The device offers precision monitoring of a single system supply voltage. It has a factory preset threshold voltage that ensures system reliability and stability without the need for external adjustments.
• Manual Reset Input: A manual reset input allows for a system reset to be triggered with an external button or logic signal, providing an additional layer of system control.
• Power-On Reset: The device generates a reset signal upon power-up, ensuring that the µP starts in a known state. The reset signal remains asserted until the supply voltage reaches the stable operating level and then maintains the reset for a period to ensure proper system boot-up.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6719UTSFD1+T operates with extremely low quiescent current, which is critical for extending battery life in portable devices.
• High Accuracy: The supervisory circuit features high threshold accuracy, which allows for precise monitoring and more reliable system operation.
• Watchdog Timer: The built-in watchdog timer ensures that the µP does not hang in an indefinite state, providing an automatic system reset in case the µP fails to provide a periodic watchdog signal.

Overall, the Maxim Integrated MAX6719UTSFD1+T is an excellent choice for designers looking for a simple, cost-effective solution for voltage monitoring and processor supervision in their digital systems. Its combination of features ensures that it can meet the demands of a wide range of applications, from consumer electronics to industrial controls.
