Diodes Incorporated

MicroProcessor Supervisory IC / Reset IC / Voltage Detector

The fundamental application of a MPS (MicroProcessor Supervisory)  / Reset IC / Voltage Detector circuit is to keep the microprocessor of a system under control. Thus a system with a good µP Supervisory circuitry can greatly enhance its quality and reliability of the product as a result. Diodes' series of µP Supervisory products provide high accuracy voltage supervisor, watchdog, power-up reset and manual reset serial function to improve the system reliability in applications such as Telecom, Networking, Security, Ultra Mobility and Wireless etc.

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.
