MAX817LCSA+

MAXIM INTEGRATED PRODUCTS  MAX817LCSA+  芯片, 微处理器监控器, 5.5V, NSOIC-8

The 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.
