Product Overview: APX810S-31SR-7

The APX810S-31SR-7 is a robust microprocessor supervisory circuit, meticulously engineered by Diodes Incorporated to ensure reliable operation of microprocessor (µP) systems. This precision device monitors the power supply voltage of digital systems, providing a significant layer of protection against low voltage conditions that can lead to system errors and failures.

Key Features

• Voltage Monitoring: This component is designed to monitor 3.1V power supplies, with a precision factory-trimmed threshold that ensures accurate voltage detection.
• Reset Signal: Upon detecting an out-of-tolerance condition, the APX810S-31SR-7 asserts a reset signal, which remains active until the system voltage stabilizes above the threshold, plus a built-in delay time. This function helps to prevent erroneous operation during power-up, power-down, and brown-out conditions.
• Low Power Consumption: The device is optimized for low power consumption, making it suitable for battery-operated applications where power efficiency is crucial.
• Compact Package: It comes in a compact SOT-23 package, which is ideal for space-constrained applications while providing excellent thermal performance.
