Microcontroller Interface With Hall Element
US Patent:
7768219, Aug 3, 2010
Filed:
Aug 19, 2008
Appl. No.:
12/194365
Inventors:
Marvin L. Kausch - Mountain View CA, US
Assignee:
Atmel Corporation - San Jose CA
International Classification:
H02P 6/04
US Classification:
31840011, 31840018, 31840038
Abstract:
A device controller system incorporates an inexpensive Hall element to detect motion of a brushless DC motor. A magnet, which is part of a motor rotor, passes by the Hall element producing a Hall voltage each rotation. The Hall voltage is coupled through an interface port to a comparator within a process controller. A microprocessor within the process controller calculates a control response based on a comparator output signal. The interface port is rapidly configured to provide signals produced from the control response as output to device drivers on the same input-output pins that receive the Hall voltage. The device drivers produce a current through fan coils producing an update in the magnetic field of each motor phase which updates the speed of the fan according to programming within the process controller. Rapid configuring and reconfiguring of the interface port allows all necessary components of the controller system to be used with a single rotational commutation cycle.

Mode Switching Rc Network
US Patent:
8395461, Mar 12, 2013
Filed:
Oct 31, 2011
Appl. No.:
13/285352
Inventors:
Marvin L. Kausch - Mountain View CA, US
Assignee:
Atmel Corporation - San Jose CA
International Classification:
H03H 7/06
US Classification:
333174, 333172
Abstract:
Various embodiments include apparatus, systems, and methods having a conductive contact configured to couple to a resistor-capacitor (RC) network, a device unit coupled to the conductive contact, and a mode switching unit to change a characteristic of a signal at the conductive contact based at least in part on an RC time constant of the RC network. The mode switching unit may switch the device unit between a first operating mode and a second operating mode based on a signal level of the signal.

Accurate Motor Speed Control
US Patent:
2008027, Nov 6, 2008
Filed:
May 3, 2007
Appl. No.:
11/743940
Inventors:
Marvin L. Kausch - Mountain View CA, US
Assignee:
ATMEL CORPORATION - San Jose CA
International Classification:
H02P 6/06, H02P 7/29
US Classification:
31840017
Abstract:
A method of and system for controlling a brushless direct current (BLDC) motor includes providing with a lookup table a predetermined corresponding desired revolution time (DRT) for the BLDC motor for an ambient temperature. A Hall device is used to measure an actual revolution time (RT) of the BLDC motor. DRT and RT are compared to change duration of a pulse width modulation (PWM) signal in response to the comparison result. The PWM signal is applied to one of two BLDC motor windings.
