The ON Semiconductor ASM810REUR is a robust voltage supervisor designed to ensure reliable operation of microprocessor (μP) systems. It is a vital component for systems that require a stable and dependable reset signal for their microprocessors and other logic systems. This device is essential for maintaining system integrity during power-up, power-down, and brown-out conditions.

The ASM810REUR operates by monitoring the supply voltage (V<sub>CC) of a system. When the V<sub>CC falls below a predefined threshold, the voltage supervisor asserts a reset signal to prevent system errors. The reset output remains asserted for a fixed timeout period after V<sub>CC rises above the threshold level, ensuring the system has adequate time to stabilize.

This voltage supervisor comes in a compact SOT-23 package, making it suitable for space-constrained applications. It features a low supply current, which is essential for battery-operated devices where power efficiency is critical. The ASM810REUR is designed to support a wide range of supply voltages, accommodating various applications and ensuring versatility in system design.

Key features of the ASM810REUR include:

• Precision Monitoring of 3V, 3.3V, and 5V Supply Voltages
• Low Supply Current of 17 μA (Typical)
• Fixed Timeout Period Ensuring System Stability
• Compact SOT-23 Packaging for Space-Saving Applications
• Temperature Range of -40°C to 85°C, Suitable for Industrial Applications

The ON Semiconductor ASM810REUR is ideal for a variety of applications, including portable devices, computers, controllers, and intelligent instruments. Its precision voltage monitoring and low power consumption make it an excellent choice for designers looking to enhance system reliability and performance. With its easy integration and robust feature set, the ASM810REUR is a go-to solution for system voltage supervision needs.
