MicroProcessor Supervisory IC / Reset IC / Voltage Detector FAQs

How do I choose the correct feature and part number in the MPS family?: Please click MPS cross reference table or all part feature table to choose correct feature according to your application or competitor part number.
Is there a replacement for an obsolete part?: Not all obsolete parts will have a direct replacement. However, we recommended that you contact your regional sales office.
What are the types of jitter?: There are several types of jitter, but the main ones are: cycle-to-cycle jitter, period jitter, half period jitter, and peak-to-peak jitter. Jitter terminology can be found in AB36: Jitter Measurement Techniques at Application Brief No. 36 or Application Note No. 27.
What are the types of reset output?: There are two types of reset output: push-pull and open-drain as different applications require. If you choose open-drain reset output, pull-up resistor should be added in application circuit. For detailed information, please refer to datasheets or application notes.
What is the lead finish for Pericom products? What about lead-free?: All Pericom's products that are not lead-free are composed of 85% Sn and 15% Pb. For lead-free products, they are composed of 100% matte Sn. Lead-free products are marked and ordered with the letter "E" suffix at the end of the part number.
Where can I find Mean Time Before Failure (MTBF) or Failures In Time (FIT) values for Pericom products?: FIT and MTBF data can be found at Pericom's Quality webpage.
Where can I find the information on your Pb-free and "Green" packaging?: Lead (Pb)-Free and Green information can be found on individual datasheets or Pb-Free & Green Page.
