Introducing the APX809S-26SA-7 Voltage Supervisor from Diodes Incorporated

The APX809S-26SA-7 is a highly precise voltage supervisor designed to ensure the reliable operation of microprocessors (μPs), microcontrollers (MCUs), and other voltage-sensitive digital systems. Manufactured by Diodes Incorporated, a leading provider in the semiconductor market, this component plays a crucial role in system management by monitoring the power supply voltage of digital systems.

This voltage supervisor is designed to maintain system integrity through its reset output feature. When the monitored supply voltage falls below the factory-programmed threshold, the APX809S-26SA-7 asserts a reset signal, holding the connected microprocessor in a reset state until the supply voltage stabilizes above the threshold. This process helps prevent erroneous operation during power up, power down, and brown-out conditions.

The APX809S-26SA-7 operates with a nominal threshold voltage of 2.6V, which is suitable for many low-voltage applications. The device is characterized for operation over the temperature range of -40°C to +85°C, making it reliable for use in various environmental conditions. The reset output of the APX809S-26SA-7 is active-low, and it is available in a space-saving SOT-23 package, which is ideal for compact PCB layouts.

Key features of the APX809S-26SA-7 include:

• Precision monitoring of 2.6V power supplies.
• Low supply current, making it energy efficient for battery-operated applications.
• 140ms (min) power-on reset pulse width, ensuring adequate time for system stabilization.
• Active-low reset output, which is compatible with most digital systems.
• Immunity to short duration reset signal glitches, enhancing system reliability.
• Available in a small SOT-23 package, which conserves board space.

The APX809S-26SA-7 is a robust solution for systems that require precise voltage monitoring and a reliable reset mechanism. Whether it's used in computers, embedded systems, or portable devices, this voltage supervisor from Diodes Incorporated is an essential component for maintaining system stability and preventing data corruption due to power supply inconsistencies.

For engineers and designers looking for a dependable voltage supervisor that combines accuracy, efficiency, and compactness, the APX809S-26SA-7 stands out as an excellent choice.
