MAXIM INTEGRATED / ANALOG DEVICES MAX803ZEXRT Microprocessor Supervisor

The MAX803ZEXR+T is a microprocessor reset circuit in a 3-pin SC-70 package. This supervisory circuit monitors power supplies in microprocessor and digital systems. It offers high reliability and low cost by eliminating external components and adjustments, making it suitable for circuits powered at 5V, 3.3V, 3V, or 2.5V. The device asserts a reset signal when the VCC supply drops below a preset threshold, maintaining the reset for at least 140ms after VCC rises above the threshold. It is widely used in computers, controllers, intelligent instruments, critical microprocessor and microcontroller power monitoring, and battery-powered devices. Key features include a supply voltage range from 1.2V to 5.5V, an operating temperature from -40°C to 125°C, an active-low, open-drain reset output, a reset threshold voltage of 2.32V, typical supply current of 12µA, transient immunity against power supply fluctuations, and no external components needed. The reset remains valid at VCC as low as 1V.
