GEORGE TOWN, Grand Cayman, Dec. 09, 2021 (GLOBE NEWSWIRE) -- O₂Micro^® International Limited (NASDAQ Global Select Market: OIIM), a global leader in the design, development and marketing of high-performance integrated circuits and solutions, today announced the grant of a patent granted to O2Micro for a battery protection system.

O2Micro was issued 20 claims under GB Patent No. 2565006 on Sep 8, 2021, for the invention of a battery protection system, which includes a sensor, a primary protection circuit, coupled to the sensor, and a secondary protection circuit, coupled to the primary protection circuit and the sensor. The sensor is configured to generate a sense signal indicative of a temperature in a battery pack when the sensor is activated. The primary protection circuit is configured to generate a synchronizing signal in a first state or a second state, sample the sense signal when the synchronizing signal is in the first state, and provide a primary protection to the battery pack based on the sense signal. A secondary protection circuit is configured to be controlled by the synchronizing signal, sample the sense signal when the synchronizing signal is in the second state, and provide a secondary protection to the battery pack based on the sense signal.

Dr. Guoxing Li, VP of Advanced Technology, O2Micro, commented, "This invention provides a cost-effective solution to enhance the battery pack temperature related protections and reach higher function safety requirements."
