The AIC809-31CUTR is a voltage monitoring circuit manufactured by Analog Integrations Corporation. It is designed to monitor the supply voltage of a system and provide a reset signal when the voltage falls below a certain threshold. This ensures that the system starts up correctly and prevents malfunctions due to undervoltage conditions.

Applications:

• Microprocessor and microcontroller systems
• Embedded systems
• Power supply monitoring
• Battery-powered devices
• Industrial control systems

Features:

• Precision voltage monitoring
• Active-low reset output
• Fixed threshold voltage
• Low supply current
• Small form factor package
• Built-in hysteresis

Benefits:

• Ensures proper system startup and prevents malfunctions due to undervoltage
• Provides a reliable reset signal to microprocessors and microcontrollers
• Monitors voltage accurately with its precision voltage monitoring capability
• Consumes minimal power, extending battery life in portable applications
• Saves board space due to its compact package

Additional Details:

The AIC809-31CUTR features a fixed threshold voltage, providing a specific voltage level at which the reset signal is asserted. The active-low reset output makes it compatible with most microprocessors and microcontrollers. Its low supply current minimizes power consumption, making it suitable for battery-powered applications. The built-in hysteresis prevents oscillations around the threshold voltage, ensuring a stable and reliable reset signal. The AIC809-31CUTR is a cost-effective and reliable solution for voltage monitoring and system reset functions. Different versions of the AIC809 series have different voltage thresholds; this particular version monitors a voltage closer to 3.1V.
