The MXD1818UR23+ from Analog Devices is part of a family of microprocessor reset circuits designed for reliable power supply monitoring in μP and digital systems. This device asserts a reset signal when the VCC supply voltage falls below a preset threshold of 2.31V, maintaining the reset for at least 100ms after VCC rises above the threshold. It features an active-low, open-drain output and is guaranteed to output the correct logic state down to +1V.
Designed for simplicity and reliability, these ICs ignore fast transients on VCC and require no external components. They operate over a wide temperature range of -40°C to 105°C and consume low power (4μA). The MXD1818UR23+ is available in a space-saving 3-pin SOT-23 package, making it ideal for portable and battery-powered equipment.
Key features include precision monitoring of power-supply voltages, a fixed reset timeout period, and power-supply transient immunity. The device is suitable for critical μP and μC monitoring applications in computers, intelligent instruments, set-top boxes, and printers.
