Patent number: 11545967Abstract: An integrated circuit (IC) includes an input/output (I/O) circuitry with a first circuitry section including I/O pins and a second circuitry section including I/O pins. The first and second circuitry sections are mutually exclusive sections of the I/O ring. The first circuitry section includes a first I/O pin configured to receive an input voltage from a first energy source and a second I/O pin connectable to an external startup capacitor. A startup circuit is coupled to the first I/O pin and the second I/O pin. Upon receiving the input voltage from the first energy source, the startup circuit enters a during the startup phase and isolates the first circuitry section from the second circuitry section, and provides charge to the external startup capacitor. In response to achieving a predetermined minimum charge on the external startup capacitor, the first circuitry section is connected to the second circuitry section, and the startup phase ends and the IC transitions to a functional mode of operation.Type: GrantFiled: August 27, 2021Date of Patent: January 3, 2023Assignee: NXP B.V.Inventors: Edwin Schapendonk, Wouter van der Heijden, Oswald Moonen, Henri Verhoeven, Ton van Deursen

Publication number: 20220329150Abstract: A controller for a DC-DC converter that includes an inductor. The DC-DC converter has three phases of operation: a first phase, in which an input voltage charges the inductor; a second phase, in which the inductor discharges to a load; and a third phase, in which the inductor is disconnected from the load and in which the input voltage does not charge the inductor. The controller is configured to set a control-factor based on the input voltage of the DC-DC converter, and set the duration of the third phase based on the control-factor and the sum of the duration of the first phase and the second phase.Type: ApplicationFiled: April 7, 2022Publication date: October 13, 2022Inventors: Wouter van der Heijden, Edwin Schapendonk, Henricus Cornelis Johannes Buthker, Henri Verhoeven, Oswald Moonen, Ton van Deursen

Patent number: 9762295Abstract: According to an aspect of the invention a system for commissioning devices is provided, which system comprises: a first device and a second device; an RFID tag comprised in the first device; a host processor comprised in the first device; wherein the second device is arranged to generate an electromagnetic field; wherein the RFID tag is arranged to detect the electromagnetic field and to wake up the host processor upon detecting said electromagnetic field in order for the second device to communicate with the host processor. Furthermore, a corresponding method for commissioning devices is provided. Since the RFID tag comprised in the first device is arranged to wake up the host processor, an end-user does not have to switch on the first device manually. Therefore, the user interaction is simplified. Furthermore, there is no need for a separate power button on the first device. The latter reduces cost and simplifies the design of the first device.Type: GrantFiled: September 19, 2012Date of Patent: September 12, 2017Assignee: NXP B.V.Inventors: Ewout Brandsma, Maarten Christiaan Pennings, Aly Aamer Syed, Timo van Roermund, Ruud Hendricksen, Oswald Moonen

Patent number: 9305455Abstract: A switch module is designed to facilitate user definition of a group of switch modules that control the same lamp. A lamp unit (12) containing the lamp responds selectively to messages from the switch modules (10, 10?) when the messages comprise ID information matching with ID information stored in the lamp unit (12). A group is formed by detecting user control operation of sensors (100) in the switch modules (10, 10?), transmitting messages from the switch modules (10, 10?) in response and determining from the messages whether the switch modules (10?) have both been operated within a time interval with a duration of less than a predetermined threshold. If so, the ID information value in memories (104) of the switch module (10) and/or the further switch module (10?) are set to matching ID values, for use in the messages to control the lamp unit.Type: GrantFiled: July 20, 2010Date of Patent: April 5, 2016Assignee: NXP B.V.Inventors: Arie Geert Cornelis Koppelaar, Oswald Moonen, Emmanuel David Lucas Michael Frimout, Ewout Brandsma, Gert-Jan Koolen

Patent number: 8810158Abstract: A lamp is provided that is controlled by messages transmitted via a network. The lamp has an internal memory that stores an address and an internal control circuit that responds to received messages that refer to this address. The address is updated when the lamp is installation in a power supply socket, using for example an address from the first message that is transmitted after installation. The lamp contains a detector that detects disconnection of the lamp from the power supply socket, for example by monitoring a resistance value between two parts of one of the power supply terminals of the lamp. In response to this detection the control circuit of the lamp sets information that enables an update of the address in the memory. When it is detected that the lamp is again connected to a power supply socket the address is updated on condition that the update is enabled.Type: GrantFiled: April 7, 2010Date of Patent: August 19, 2014Assignee: NXP, B.V.Inventors: Arie Geert Cornelis Koppelaar, Oswald Moonen, Emmanuel David Lucas Michael Frimout, Aly Aamer Syed, Paul Mattheijssen, Ewout Brandsma, Gert-Jan Koolen
