MAXIM INTEGRATED / ANALOG DEVICES MAX814LCSA High-Accuracy Supervisory Circuit

The MAX814LCSA+ is a high-accuracy microprocessor supervisory circuit in an 8-pin NSOIC package. It provides essential power-on reset and power-fail functions, ensuring reliable operation in critical applications by eliminating manual trimming and maintaining high reset threshold accuracy. The circuit features a reset comparator designed to ignore fast VCC transients, with the RESET output remaining in the correct state down to VCC levels as low as 1V. It is suitable for use in controllers, intelligent instruments, microprocessor power monitoring, and set-top boxes. The device operates over a supply voltage range of 1V to 5.5V, with a temperature range from 0°C to 70°C. It offers a typical reset threshold of 4.7V with ±1% accuracy, a 200ms reset time delay, and a maximum supply current of 75μA. Additional features include active low RESET, active high RESET, manual reset input, power supply glitch immunity, and a ±2% power-fail comparator with a low line threshold accuracy within 60mV above the reset threshold.
