Patent number: 9735577Abstract: A Maintain Power Signature (MPS) Powered Device (PD) is described. In one or more implementations, the MPS device comprises a current sensor configured to sense current flowing from Power Sourcing Equipment (PSE) to the PD. The current sense based MPS device also comprises a current generator configured to sink electrical current to prevent the PSE from removing power to the PD. Thus, the electrical current comprises a current amplitude characteristic selected based upon MPS requirements of the PSE. In some implementations, the current is sunk to a ground. In other implementations, the current is sunk to a storage device, such as a storage device included with the PD and/or external to the PD.Type: GrantFiled: October 5, 2015Date of Patent: August 15, 2017Assignee: Maxim Integrated Products, Inc.Inventors: Cristian Cerutti, Phillip J.

Patent number: 9477634Abstract: Embodiments of the present invention relate to systems, devices and methods for translating I2C addresses. In accordance with an embodiment, a method for translating an I2C address includes receiving an original I2C address from a first I2C compatible device via an I2C-bus to which the first I2C compatible device is connected. The method also includes translating the original I2C address to a translated I2C address, and outputting the translated I2C address to a second I2C compatible device via a secondary side of the I2C-bus to which the slave device is connected. The original I2C address can be translated to the translated I2C address by subtracting an offset value from (or adding an offset value to) the original I2C address to produce the translated I2C address. Such an offset value can be specified using pin strapping, or by storing the offset value in a register or non-volatile memory that is programmable via the—I2C bus.Type: GrantFiled: March 11, 2011Date of Patent: October 25, 2016Assignee: INTERSIL AMERICAS LLCInventors: David B.

Patent number: 8167485Abstract: Methods and systems for producing a digital temperature reading are provided. In an embodiment, one or more current sources and one or more switches are used to selectively provide a first amount of current (I1) and a second amount of current (I2) to the emitter of a transistor (Q1), during different time slots of a time period, to thereby produce a first base-emitter voltage (Vbe1) and a second base-emitter voltage (Vbe2), where I1=I2*M, and M is a known constant. An analog-to-digital converter (ADC) digitizes analog signals representative of the magnitudes Vbe1 and Vbe2. A difference is determined between the magnitudes of Vbe1 and Vbe2. A digital calculator produces a digital temperature reading (DTR) based on the difference between the magnitudes of Vbe1 and Vbe2.Type: GrantFiled: September 16, 2009Date of Patent: May 1, 2012Assignee: Intersil Americas Inc.Inventors: Xijian Lin, Phillip J.

Patent number: 7960807Abstract: A CMOS light detector configured to detect specific wavelengths of light includes a first sensor and a second sensor. The first sensor includes CMOS photocells that are covered by a colored filter layer of a first color that has a first transmittance that allows both light of the specific wavelengths and light of other wavelengths to pass. The second sensor including further CMOS photocells, at least some of which are covered by both a colored filter layer of the first color and a colored filter layer of a second color, stacked one above the other in either order, where the colored filter layer of the second color has a second transmittance that allows light of the other wavelengths to pass. The first sensor produces a first photocurrent, and the second sensor produces a second photocurrent, when light including both the specific and other wavelengths is incident upon the detector.Type: GrantFiled: March 14, 2007Date of Patent: June 14, 2011Assignee: Intersil Americas Inc.Inventors: Xijian Lin, Phillip J.

Patent number: 7956432Abstract: A photodiode includes a substrate having a first semiconductor type surface region on at least a portion thereof, and a second semiconductor type surface layer formed in a portion of the surface region. A multi-layer anti-reflective coating (ARC) is on the second semiconductor type surface layer, wherein the multi-layer ARC comprises at least two different dielectric layers. A layer resistant to oxide etch is above a peripheral portion the multi-layer ARC. Further layers are above the layer resistant to oxide etch, and thereby above the peripheral portion the multi-layer ARC. A window extends down to the multi-layer ARC. A photodiode region is formed by a pn-junction of the first semiconductor type surface region and the second semiconductor type surface layer.Type: GrantFiled: February 3, 2009Date of Patent: June 7, 2011Assignee: Intersil Americas Inc.Inventors: Dong Zheng, Phillip J.

Patent number: 7907061Abstract: In an embodiment, a proximity sensor includes a driver, a photo-diode (PD) and an analog-to-digital converter (ADC). The proximity sensor can also include a controller to control the driver. The driver selectively drives a light source, e.g., an infrared (IR) light emitting diode (LED). The PD, which produces a current signal indicative of the intensity of light detected by the PD, is capable of detecting both ambient light and light produced by the light source that is reflected off an object. The ADC receives one or more portion of the current signal produced by the PD. The ADC produces one or more digital output that can be used to estimate the proximity of an object to the PD in a manner that compensates for ambient light detected by the PD and transient changes to the detected ambient light.Type: GrantFiled: April 10, 2008Date of Patent: March 15, 2011Assignee: Intersil Americas Inc.Inventors: Xijian Lin, Zhong Li, Wendy Ng, Phillip J.
