MAX6305MAX6313 19-1145 Rev 6 7/12 5-Pin, Multiple-Input, Programmable Reset ICs General Description Features The MAX6305MAX6313 CMOS microprocessor (P) Small 5-Pin SOT23 Package supervisory circuits are designed to monitor more than Precision Factory-Set V Reset Thresholds CC 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 V Transients CC assert a system reset if any of the monitored supplies Guaranteed RESET Valid to V = 1V CC falls outside the programmed threshold. Low supply Guaranteed Over Temperature current (15A) and a small package suit them for portable applications. The MAX6305MAX6313 are 8A Supply Current specifically designed to ignore fast transients on Factory-Set Reset Timeout Delay from any monitored supply. 1ms (min) to 1120ms (min) These devices are available in a SOT23-5 package, No External Components have factory-programmed reset thresholds from 2.5V to Manual Reset Input 5.0V (in 100mV increments), and feature four power-on Under/Overvoltage Supply Monitoring reset timeout periods. Ten standard versions are avail- able. Contact the factory for availability of non standard Ordering Information versions.

Insert the desired nominal reset threshold (from Table 1) into the blanks following the letters UK. Portable/Battery-Powered Equipment All parts also offer factory-programmed reset timeout periods. Multivoltage Systems: 3V/5V, 5V/12V, 5V/24V Insert the number corresponding to the desired nominal timeout period index following the D in the part number (D1 = 1ms min, Embedded Control Systems D2 = 20ms min, D3 = 140ms min, and D4 = 1120ms min). There are 10 standard versions with a required order increment of 2,500 pieces. Sample stock is generally held on the standard versions only (see Standard Versions table). Required order increment is Pin Configurations and Typical Operating Circuit appear at 10,000 pieces for non-standard versions.
