AIC809-31PU Description

Short technical summary and product information.

The AIC809-31PU is a 3-pin microprocessor supervisory circuit designed by Analog Integrations Corporation (AIC) to monitor power supplies in microprocessor and digital systems. It offers circuit reliability and cost benefits by eliminating external components.

Key electrical specifications include an ultra-low supply current of 1µA (typical) and guaranteed reset validity down to 0.9V. The device features an internally fixed threshold voltage of 3.1V with a tight tolerance of 1.5%. The power-on reset pulse width is a minimum of 140ms, ensuring stable system operation when the VCC supply voltage drops below the preset threshold.

This supervisor is suitable for applications requiring critical microprocessor monitoring, such as notebook computers, digital still cameras, and PDAs. Its low power consumption makes it ideal for portable equipment. The AIC809-31PU is available in a compact SOT-23 package, suitable for surface mount applications.

The AIC809/AIC810 series offers different output types, including push-pull active low (AIC809), push-pull active high (AIC810), and open-drain active low (AIC809N). The AIC809-31PU is a specific configuration within this series, designed for reliable power supply supervision.
