The APX809S-23SA-7 is a highly reliable, low-power microprocessor supervisory circuit, meticulously engineered by Diodes Incorporated to maintain system integrity during power fluctuations. This compact component is an essential part of any microprocessor-based system, ensuring that the processor and associated peripherals are reset to a known state during power-up, power-down, and brown-out conditions.

Key Features

• Precision Monitoring: With a factory-trimmed threshold voltage of 2.3V, the APX809S-23SA-7 provides precise voltage monitoring, making it suitable for systems that require consistent operation and high stability.
• Low Power Consumption: Designed for energy-sensitive applications, the device operates with a very low quiescent current, thereby reducing the overall power consumption of the system.
• Manual Reset Input: The inclusion of a manual reset input allows for a system reset to be initiated at any time, providing additional control and security for system maintenance or emergency interventions.
• Power Supply Glitch Immunity: The APX809S-23SA-7 ensures that temporary power supply glitches do not cause false resets, thereby improving the reliability of the system it protects.
• Output Configuration: The reset output is active-low and is available in a push-pull configuration, which eliminates the need for an external pull-up resistor and simplifies design.
