Patent number: 8344817Abstract: A compensating DFLL (CDFLL) is disclosed that utilizes temperature readings at regular intervals in combination with production characterization data of a reference oscillator to compensate for frequency drift and nominal frequency error. In some implementations, the CDFLL selects a calibration value that is not optimal for frequency accuracy to minimize accumulated frequency error over time. More particularly, during a calibration run, mismatch between an ideal frequency and an actual frequency is measured, and the measurement is used as a starting point for a next calibration run, such that the accumulated frequency error is averaged almost to zero over time.Type: GrantFiled: December 22, 2010Date of Patent: January 1, 2013Assignee: Atmel CorporationInventors: Arne Aas, Andreas Onsum

Publication number: 20120170157Abstract: A battery management and protection system can include various features to improve safety-critical and other functions. Among the features that can be included in some implementations are automatic loading of safety or other parameters during start-up of the system; a centralized timekeeper and an event system that can trigger actions in the system independently of a central processing unit; use of the same modules for both automatically-controlled safety-related measurements and firmware-controlled measurements; enhanced diagnostic features, and a sleepwalking feature that allows certain modules in the system to continue to perform various functions even when the module or the system is in a low-power sleep mode.Type: ApplicationFiled: March 2, 2012Publication date: July 5, 2012Applicant: Atmel CorporationInventors: Eivind Holsen, Andreas Onsum, Odd Jostein Svendsli, Arne Aas

Patent number: 8143860Abstract: A microcontroller is disclosed. The microcontroller comprises a processor system and a high voltage interface coupled to the processor system and adapted to be coupled to a battery. The microcontroller further includes a battery management system for monitoring the battery and managing the battery based upon the monitoring of the battery. The microcontroller is a single chip. This one-chip solution saves design cost and PCB space in addition to broadening the functionality of the smart battery application. With the accuracy of the microcontroller, the charge status of the battery can be predicted more accurately and therefore effectively increases actual battery capacity.Type: GrantFiled: July 19, 2010Date of Patent: March 27, 2012Assignee: Atmel CorporationInventors: Gunnar Gangsto, Arne Aas, Runar Sorasen

Publication number: 20120046894Abstract: A method and system utilized with an analog to digital converter is disclosed. The method and system comprise providing a first conversion on an input signal. In the first conversion, an offset error is added to the input signal to provide a first result. The method and system further includes providing a second conversion on the input signal. In the second conversion, an offset error is subtracted from the input signal to provide a second result. The first and second results are then combined to substantially remove the offset error. A system and method in accordance with the present invention compensates for the accumulated offset error over many samples, thereby achieving much higher accuracy in the offset error compensation.Type: ApplicationFiled: October 31, 2011Publication date: February 23, 2012Inventors: Arne Aas, Gunnar Gangstoe, Torgeir Fenheim

Patent number: 7629769Abstract: A battery pack can include one or more battery cells, current blocking transistors and a battery management system. The disclosed implementations handle over-currents drawn from the battery cells that cause unstable operation of the battery management system. The over-currents are handled without causing an undesired drop in voltage output from the battery cells. The disclosed implementations can handle over-currents even if the over-currents cause the battery management system supply voltage to drop below a minimum operating voltage level for a certain period of time. The disclosed implementations use current blocking transistors that can be configured to block current flow and ensure safe operation of the battery cells in cases where the current drawn from the battery cells would be sufficiently high for a sufficiently long period of time to cause damage to the battery cells.Type: GrantFiled: March 10, 2006Date of Patent: December 8, 2009Assignees: Atmel Corporation, Sony CorporationInventors: Gunnar Gangstoe, Hideyuki Sato, Arne Aas, Terje Saether
