Product Overview: APX810S-46SR-7

The APX810S-46SR-7 is a highly reliable, precision microprocessor (μP) supervisory circuit designed by Diodes Incorporated to monitor the power supply performance in digital systems. It ensures that the system's microprocessor is reset to a known state during power-up, power-down, or if a brown-out condition occurs. This supervisory circuit is especially crucial in applications where safe operation is essential, and the system needs to be protected against unpredictable power supply variations.

Key Features

• Precision Monitoring: The device features a precise threshold voltage of 4.63V, tailored for 5V systems, ensuring accurate monitoring and control of the power supply.
• Low Power Consumption: With its low power draw, the APX810S-46SR-7 is suitable for energy-sensitive applications, minimizing the overall power consumption of the system.
• Reset Timeout Delay: It provides a 140ms minimum reset timeout delay, offering a sufficient window for the system to stabilize before normal operation resumes.
• High Threshold Accuracy: The device maintains a threshold accuracy of ±2.5%, which ensures reliable reset activation even under temperature variations ranging from -40°C to +105°C.

Applications

The APX810S-46SR-7 is ideal for a wide range of applications where reliable system operation is critical. These include:

• Computers and Computer Peripherals
• Embedded Systems
• Microcontroller Systems
• Intelligent Instruments
• Portable/Battery-Powered Equipment

Package and Availability
