19-1145; Rev 1; 8/98 5-Pin, Multiple-Input, Programmable Reset ICs General Description Features The MAX6305–MAX6313 CMOS microprocessor (µP) ¦ Small 5-Pin SOT23 Package supervisory circuits are designed to monitor more than ¦ Precision Factory-Set VCC Reset Thresholds; one power supply. Ideal for monitoring both 5V and Available in 0.1V Increments from 2.5V to 5V 3.3V in personal computer systems, these devices ¦ Immune to Short VCC Transients assert a system reset if any of the monitored supplies falls outside the programmed threshold. Low supply ¦ Guaranteed RESET Valid to VCC = 1V current (15µA) and a small package suit them for ¦ Guaranteed Over Temperature portable applications. The MAX6305–MAX6313 are ¦ 8µA Supply Current specifically designed to ignore fast transien
