MAXIM INTEGRATED / ANALOG DEVICES MAX818LESA Microprocessor Supervisory Circuit

The MAX818LESA+ is a 5V microprocessor supervisory circuit housed in an 8-pin NSOIC package. It simplifies power supply monitoring, battery control, and chip-enable gating in microprocessor systems by reducing component count. Specifically designed for +5V systems, it features a low supply current of 11µA (typical) and a compact size, making it ideal for embedded controllers, intelligent instruments, and critical microprocessor monitoring. The device supports a voltage supply range from 0V to 5.5V, with an operating temperature range from -40°C to 85°C. It provides a precision voltage monitor at 4.65V, a 200ms reset delay, and an active-low reset output. Additional features include battery backup power switching (with battery voltage capable of exceeding VCC), onboard 3ns gating of chip-enable signals, a watchdog timer with a 1.6-second timeout, and a power-fail comparator. Suitable applications include system monitoring and portable devices.
