Item 5.  Other Events.


   Micrel, Incorporated  (the "Company") today filed a complaint against
Deloitte & Touche LLP ("Deloitte") entitled Micrel, Incorporated v. Deloitte &
Touche LLP in the Superior Court of the State of California, County of Santa
Clara, alleging various causes of action relating to certain professional
advice received by Micrel from Deloitte. In this lawsuit, Micrel is alleging
that Deloitte negligently rendered services as accountants to Micrel, breached
certain agreements with Micrel by failing to perform services using ordinary
skill and competence and in conformance with generally accepted principles for
such work and made certain false representations upon which Micrel justifiably
relied.   As a direct result of Deloitte's actions, Micrel alleges damages
including: expenses incurred in the form of payments to various professionals
to address the impact on Micrel's financial statements and other effects of
the wrongful conduct; loss of cash as well as equity from stock options;
additional charges to earnings that Micrel would not incur but for the
wrongful advice; additional potential liability for taxes; potential liability
for tax penalties; and the harm to Micrel in both financial and semiconductor
markets resulting in loss of overall value of the company as a whole.  The
complaint seeks compensatory damages, costs of suit and such other relief that
the court may deem just and proper.
