Maxim Integrated's MAX706PESA+T: Robust Microprocessor Supervisory Circuit

The MAX706PESA+T from Maxim Integrated is a compact, highly-reliable supervisory circuit designed to monitor microprocessor (µP) systems for proper operation. Engineered to maintain system integrity, this device keeps a vigilant watch over power supply levels and µP activity, ensuring that all system parameters remain within operational thresholds.

Key Features

• Power Supply Monitoring: The MAX706PESA+T provides precise monitoring of the power supply voltage. It generates a reset signal to the µP whenever the VCC supply voltage falls below its reset threshold level, ensuring the µP restarts cleanly during power-up, power-down, or brown-out conditions.
• Manual Reset Capability: An additional feature of this supervisory circuit is its manual reset input, which allows for a system reset to be initiated by an external signal, providing an extra layer of control.
• Low Power Consumption: Designed for power-sensitive applications, this device consumes minimal power, with a typical quiescent current of only 17µA, making it suitable for battery-operated devices.
• Watchdog Timer: The integrated watchdog timer ensures that the µP does not hang in a runaway or indefinite loop. If the µP does not provide a periodic signal to the MAX706PESA+T, the device will issue a system reset, prompting a return to a known state.
• Versatile Operating Range: This supervisory circuit operates over a wide voltage range, accommodating systems that require different levels of power supply.
• Extended Temperature Range: The MAX706PESA+T is designed to operate across an extensive temperature range, making it suitable for industrial applications where environmental conditions may vary.

Applications

• Computers and Servers
• Embedded Systems
• Industrial Controllers
• Portable/Battery-Powered Equipment

The MAX706PESA+T is delivered in a compact 8-pin SOIC package, ensuring a small footprint on system boards. Its robust design and comprehensive feature set make it an essential component for any microprocessor-based system requiring reliable monitoring and reset capabilities. Maxim Integrated's commitment to quality ensures that this supervisory circuit will enhance the operational stability and safety of your electronic products.
