The APX809S-29SR-7 is a microprocessor supervisory circuit that provides a compact, streamlined solution for system reset and power management. Manufactured by Diodes Incorporated, this device is specifically designed to monitor the system voltage and maintain the proper operation of microprocessors (µPs), microcontrollers (MCUs), and digital signal processors (DSPs) within embedded systems.

Key Features

• Precision Voltage Monitoring: The APX809S-29SR-7 is equipped with a precision voltage reference and comparator circuit to monitor the Vcc/Vdd levels and ensure that they remain within the acceptable range for reliable system operation.
• Programmable Reset Threshold: The device has a fixed reset threshold voltage of 2.93V, which is suitable for operation with 3.3V power supplies, ensuring compatibility with a wide range of microprocessor-based applications.
• Low Power Consumption: Designed for power-sensitive applications, the APX809S-29SR-7 offers low power consumption, thereby reducing the overall energy footprint of the system it is integrated into.
• Reset Output: The active-low reset output is guaranteed to remain asserted for a minimum of 140ms after Vcc has risen above the reset threshold level, providing a reliable reset signal to the host system.
• Temperature Range: This device is operational over a wide temperature range, making it suitable for use in diverse environmental conditions.
• Package: It comes in an SOT-23 package, which is known for its small footprint, allowing for high-density mounting and saving valuable board space in compact electronic assemblies.

Applications

The APX809S-29SR-7 is versatile and can be used in a variety of applications where reliable system reset functionality is crucial. It is particularly useful in portable devices, computers, controllers, intelligent instruments, and other digital systems that require voltage monitoring to prevent data corruption and ensure the proper initialization during power-up or brown-out conditions.
