General Description

The MAX6305¨CMAX6313 CMOS microprocessor (?P) supervisory circuits are designed to monitor more than one power supply. Ideal for monitoring both 5V and 3.3V in personal computer systems, these devices assert a system reset if any of the monitored supplies falls outside the programmed threshold. Low supply current (15?A) and a small package suit them for portable applications. The MAX6305¨CMAX6313 are specifically designed to ignore fast transients on any monitored supply.
