Additional Details

The ADM811ZARTZRL7 features a fixed threshold voltage, which is factory-trimmed for accuracy. The active-low reset output asserts when the input voltage falls below the threshold and remains asserted for a specified period after the voltage recovers. A manual reset input allows for external triggering of the reset. The device is available in a small SOT-23 package, making it suitable for compact designs. Its low supply current ensures minimal power consumption, extending battery life in portable devices. The ADM811 provides a cost-effective and reliable solution for voltage monitoring and reset generation in a wide range of applications. The device ensures that the system is properly initialized and protected from potentially damaging voltage fluctuations. The internal circuitry provides hysteresis to prevent oscillations near the threshold voltage.
