MAX706

The MAX706 is a microprocessor (µP) supervisory circuit designed to monitor the power supply and ensure reliable operation of microprocessor systems. It provides power-on reset, watchdog timer, and battery backup switching functions. The MAX706 ensures that the microprocessor is reset whenever the supply voltage drops below a preset threshold, and it maintains the reset state until the supply voltage stabilizes. Additionally, it includes a watchdog timer to reset the system if it becomes unresponsive and a manual reset input.

Key Features:

• Monitors power supply and generates reset signal
• Precision voltage monitoring (±1.5% accuracy)
• Available with different reset threshold voltages
• Watchdog timer with selectable timeout periods
• Manual reset input
• Battery backup switching
• Low quiescent current
• Small 8-pin SOIC/DIP package

Technical Specifications:

• Supply Voltage (VCC): 1.2V to 5.5V
• Reset Threshold Voltages: Available in multiple options (e.g., 2.63V, 2.93V, 3.08V, 4.00V, 4.38V, 4.63V)
