Frequently asked questions

Is Micrel still in business?

Micrel (MIC power and LDO regulators, KSZ Ethernet switches and PHYs, SY clock and timing) was acquired by Microchip Technology in 2015.

Can I still buy Micrel parts?

Yes. PartnerSemi quotes Micrel part numbers, including obsolete and end-of-life parts and parts with old Micrel markings. Send the part number and quantity; we reply with price, lead time, date code and origin. We are an independent distributor, not an authorized Micrel or Microchip Technology distributor.
