MAX818LESA+

The MAX818LESA+ is a +5V microprocessor supervisory circuits in 8 pin NSOIC package. This microprocessor (µP) supervisory circuit simplify power-supply monitoring, battery control and chip-enable gating in µP systems by reducing the number of components required. It is specifically designed to ignore fast transients on VCC and for use in +5V powered systems. The Low supply current of 11µA (typical) and small package size makes device ideal for embedded controllers, intelligent instruments and critical µP monitoring.
