Maxim Integrated's MAX6737XKTGD3+T Microprocessor Supervisory Circuits

The MAX6737XKTGD3+T from Maxim Integrated 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 a variety of electronic applications, including computers, controllers, and intelligent instruments.

This robust device ensures that the µP is only operational when the system voltage is within an acceptable range. It achieves this by providing a reset signal to the µP during power-up, power-down, and brown-out conditions. The reset signal remains asserted until the system voltage has stabilized and the internal timer has expired, ensuring a proper system reset and preventing system errors and data corruption.

Key Features:

• Adjustable Reset Threshold Voltage: This feature allows designers to set the threshold according to the specific needs of their system, ensuring compatibility with a wide range of microprocessors and other digital ICs.
• Manual Reset Input: The inclusion of a manual reset input provides an additional level of control, allowing for a system reset to be triggered by external events or user intervention.
• Power-Supply Transient Immunity: The MAX6737XKTGD3+T is designed to ignore fast transients on the VCC line, which helps to prevent false resets and ensures stable operation even in noisy environments.
• Low Power Consumption: With its low quiescent current, this supervisory circuit is an ideal choice for power-sensitive applications, helping to extend the battery life of portable devices.
• Immune to Short VCC Transients: The robust design ensures that the device is unaffected by short-duration transients on the power supply line, maintaining the integrity of the system.

Available in a small, 5-pin SOT23 package, the MAX6737XKTGD3+T is designed for space-constrained applications. It is also specified over the extended -40°C to +125°C temperature range, making it suitable for use in harsh environments. With its combination of features, this supervisory circuit from Maxim Integrated is an excellent choice for ensuring the reliable operation of your digital systems.
