MAX6309UK32D1-T

5引脚，多输入，可编程复位IC 5-Pin, Multiple-Input, Programmable Reset ICs

General Description

The MAX6305–MAX6313 CMOS microprocessor µP 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 15µA and a small package suit them for portable applications. The MAX6305–MAX6313 are specifically designed to ignore fast transients on any monitored supply.
