The MAX6734KALTD3/V+T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered circuits.

This supervisory circuit ensures that the microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6734KALTD3/V+T features a variety of factory-trimmed reset thresholds, making it suitable for monitoring 3V, 3.3V, and 5V power supplies. Additionally, the device has a manual reset input, which provides a robust level of control to the system designer.

The MAX6734KALTD3/V+T offers an adjustable reset timeout delay, which can be set by an external capacitor. This flexibility allows designers to tailor the reset assertion time to match system requirements. Moreover, the device has a low supply current, which makes it ideal for use in portable equipment where power conservation is critical.

Key features of the MAX6734KALTD3/V+T include:

• Factory-trimmed V_CC reset thresholds for 3V, 3.3V, and 5V supplies
• Adjustable reset timeout delay via an external capacitor
• Manual reset input for additional system control
• Low supply current ideal for battery-powered applications
• Immunity to short V_CC transients
• Wide operating temperature range

This device is available in a compact 8-pin SOT23 package, making it suitable for space-constrained applications. With its wide operating temperature range, the MAX6734KALTD3/V+T is designed to perform reliably in a variety of environments, ensuring that systems continue to operate safely and effectively under various conditions.

Whether used in computers, controllers, intelligent instruments, or portable consumer products, the MAX6734KALTD3/V+T from Maxim Integrated provides a simple and efficient solution for system reset and power monitoring, enhancing overall system stability and performance.
