The APX810S05-46SR-7 from Diodes Incorporated is a highly reliable, precision microprocessor (µP) supervisory circuit designed to monitor the power supplies in digital systems. It provides a significant function in ensuring system integrity by managing the reset activity for the connected microprocessor. This component is essential for applications that require a stable and reliable operation over a wide range of environmental conditions.

Key Features

• Voltage Monitoring: The APX810S05-46SR-7 actively monitors the VCC and triggers a reset signal to the µP whenever VCC falls below the minimum voltage threshold of 4.63V, ensuring proper system reboot and preventing system failures.
• Reset Timeout: It features a 140 ms minimum reset timeout duration, which provides ample time for the system to stabilize before the microprocessor starts its operation after a reset event.
• Low Power Consumption: With its low power consumption, this supervisory circuit is an excellent choice for power-sensitive applications, contributing to overall energy efficiency.
• High Accuracy: The reset threshold accuracy is maintained at ±1.5%, which ensures reliable reset activation and system stability.
• Operating Temperature: It operates over a wide temperature range from -40°C to +85°C, making it suitable for various industrial and commercial environments.

Applications

The APX810S05-46SR-7 is ideal for use in a variety of applications that require accurate and reliable system reset functionality. This includes:

• Computers and Servers
• Embedded Systems
