Patent number: 11935719Abstract: A power switch controller includes a condition detector, a zero crossing detector, a retimer, and a driver. The condition detector detects a change in a sense signal towards a first or second condition. The zero crossing detector detects zero crossings in an AC powerline signal. The power switch controller drives a latching relay that connects a load to powerlines. The power switch controller activates or deactivates the latching relay based on the sensed condition, and retimes activation and deactivation pulses to align the relay contact opening and closing times to coincide with the AC powerline zero crossings, compensating for contact travel times. The activation and deactivation pulses have a duration of max 20 ms, and an amplitude of at least 110% of the maximum sustainable voltage for the relay coil(s). A power-on reset deactivates the relay, aligned with a second AC zero crossing.Type: GrantFiled: August 11, 2022Date of Patent: March 19, 2024Assignee: SiliconBrite Technologies, Inc.Inventors: Cameron Nathan Jackson, Baris Karagozlu, Alexander Burinskiy

Patent number: 8665668Abstract: Technologies are generally described for an integrated circuit that is designed to serve as the basis of SONAR sensors that provide high sensitivity, low noise, low cost, and electronically adjustable gain in a small package may incorporate transducer drivers and signal sensing functions. Electronically programmable gain of the circuit may provide flexibility in system designs for gain management, and eliminate a need for manual gain adjustments in production. Power may be supplied to the sensor(s) over a power line of the circuit from a direct current source through a resistor. The same line may also be used for communicating with the sensor(s). Data from the microcontroller may be transmitted to the sensor(s) using an open-drain driver transistor and received through another transistor isolating the micro-controller's input from potentially high voltages present on the power line.Type: GrantFiled: September 13, 2011Date of Patent: March 4, 2014Assignee: Vivid Engineering, Inc.Inventors: Vladislav Potanin, Alexander Burinskiy, Elena Potanina

Patent number: 8446187Abstract: A power-on reset (POR) circuit is provided. The POR circuit includes a first current source, a second current source, and a current comparator. The first current source is arranged to provide a relatively supply-independent circuit. The second current source is arranged to provide a supply-dependent current. The current comparator is arranged to compare the relatively supply-independent circuit with the relatively supply-dependent current to provide a POR signal.Type: GrantFiled: November 16, 2007Date of Patent: May 21, 2013Assignee: National Semiconductor CorporationInventor: Alexander Burinskiy

Patent number: 8331005Abstract: A method for providing feed forward compensation in a drive signal for a rapid resonant frequency change due to a rapid LASER intensity change upon a micro-electro-mechanical system (MEMS) mirror and/or a surrounding MEMS structure in a MEMS scanner causing a mirror temperature change is provided. The method includes determining an intensity factor for at least one laser beam projected onto the MEMS scanner and adjusting a drive frequency of the drive signal based on the intensity factor. The intensity could represent a single intensity factor for multiple laser beams projected onto the MEMS scanner. The method could also include delaying the adjustment of the drive frequency to allow the resonant frequency change to take affect in the MEMS scanner. Delaying the adjustment could include delaying delivery of the intensity factor such that the intensity factor is provided coincident with the resonant frequency change of the MEMS scanner.Type: GrantFiled: April 23, 2010Date of Patent: December 11, 2012Assignee: National Semiconductor CorporationInventors: Alexander Burinskiy, James Steven Brown

Patent number: 7800127Abstract: In an ESD device for fast switching applications based on a BSCR or NLDMOS-SCR, an anode junction control electrode is provided by not connecting the anode electrode to the collector of the BSCR or to the drain of the NLDMOS-SCR, and a cathode junction control electrode is provided by forming an additional n+ region in the BSCR or an additional p+ region in the p-well of the NLDMOS-SCR. The triggering voltage of the ESD device is adjusted after a time delay by controlling one or both of the control electrodes using an RC-timer-driver circuit.Type: GrantFiled: August 14, 2006Date of Patent: September 21, 2010Assignee: National Semiconductor CorporationInventors: Vladislav Vashchenko, Alexander Burinskiy, Peter J.

Patent number: 7671574Abstract: A buck DC to DC converter is arranged to more accurately regulate an output voltage by substantially eliminating a ground voltage error caused at least in part by parasitic resistance during low side conversion/regulation. During high side conduction of the high side switch, the converter employs the output voltage for error correction. And during low side conduction of the low side switch, the converter employs a sampled and held version of the output voltage for error correction which enables the converter to eliminate the ground voltage error caused by parasitic resistance.Type: GrantFiled: May 30, 2007Date of Patent: March 2, 2010Assignee: National Semiconductor CorporationInventors: Alexander Burinskiy, Frank De Stasi

Patent number: 7271626Abstract: A multi-stage transistor circuit is provided in which the multiple transistor stages are coupled in parallel and switched individually in sequence by a series arrangement of buffers. Each buffer drives the gate of a corresponding stage of the multi-stage transistor circuit with a gating signal that is delayed by each buffer. Optionally, the voltage of the gating signal can be varied. Each transistor stage may comprise one or more transistors in parallel. A switched capacitor DC/DC converter incorporating the multi-stage transistor circuit is provided in which parasitic ringing at the output is substantially reduced or eliminated. Additionally, the multi-stage transistor circuit is well suited for implementing an adaptive non-overlapping gating signal generator for complementarily driving a series arrangement of multi-stage transistors.Type: GrantFiled: October 27, 2004Date of Patent: September 18, 2007Assignee: National Semiconductor CorporationInventors: Alexander Burinskiy, Nathanael Griesert, Arun Rao, William J.

Patent number: 7015745Abstract: A circuit for regulating a sensed current in a power transistor is provided. The circuit is configured to sense if the drain current of the power transistor has reached a limit current Ilimit. A sense transistor is arranged in an m:1 current mirror relationship with the power transistor. Additionally, a current sink that is coupled to the drain of the sense current is also configured to sink a current approximately equal to Ilimit/m. Further, a comparison circuit is configured to compare the drain voltages of the power and sense transistors. Also, if the drain current of the power transistor is less than Ilimit, a current sink pulls down the drain of the sense transistor, so that the drain voltage of the sense transistor is less than the drain voltage of the power transistor. However, if the level of the drain current of the power transistor reaches Ilimit, then Vds of the sense transistor would reach Vds of the power transistor, and the comparator would trip.Type: GrantFiled: February 18, 2004Date of Patent: March 21, 2006Assignee: National Semiconductor CorporationInventors: Alexander Burinskiy, Luan Vu
