Maxim Integrated MAX6846KASD3+T Microprocessor Supervisory Circuits

The MAX6846KASD3+T is a state-of-the-art microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering. This compact, high-precision device is engineered to monitor power supplies in µP and digital systems, providing excellent circuit reliability and low power consumption.

Designed to maintain system integrity, the MAX6846KASD3+T supervisory circuit ensures that the µP boots up in a predictable state. It achieves this by monitoring the system voltage and asserting a reset signal whenever the monitored voltage drops below a preset threshold. The reset signal remains asserted until the system voltage recovers and stabilizes above the threshold, ensuring the µP starts up correctly every time.

This supervisory circuit features a factory-trimmed reset threshold voltage tailored to the specific needs of 3V-powered systems. Its accuracy and low power consumption make it an ideal choice for portable and battery-operated devices. The MAX6846KASD3+T is also characterized by its low supply current, typically just 1.2µA at +3.0V, which contributes to the overall energy efficiency of the system it is integrated into.

Key features of the MAX6846KASD3+T include:

• Factory-trimmed V_CC reset threshold voltage suitable for 3V-powered systems.
• Low supply current, enhancing battery life in portable applications.
• Manual reset input, providing a simple way to initiate a system reset.
• Debounced push-pull reset output, ensuring a clean reset signal.
• Compact SOT package, ideal for space-constrained applications.

The MAX6846KASD3+T is provided in a small, 4-pin SOT-143 package, making it easy to incorporate into a variety of designs without significant impact on the overall footprint. The device is also fully specified over the extended -40°C to +125°C temperature range, ensuring reliable operation across a wide range of environmental conditions.

With its combination of precision, low power, and compact size, the MAX6846KASD3+T from Maxim Integrated is an excellent choice for designers looking to enhance the reliability and efficiency of their µP-based systems.
