Patent number: 10868537Abstract: Embodiments relate to a circuitry for digital data communication. The circuitry includes an inverter circuit connected between an input node and an output node. The inverter circuit has core circuits each of which includes a complementary metal-oxide-semiconductor (CMOS) transistor of a first type and a CMOS transistor of a second type having a first common gate node connected to the input node and a first common drain node connected to the output node. The circuitry further includes another inverter circuit of a switching threshold voltage different than that of the inverter circuit and connected between the input node and the output node. The other inverter circuit has core circuits each of which includes a CMOS transistor of a third type and a CMOS transistor of a fourth type having a second common gate node connected to the input node and a second common drain node connected to the output node.Type: GrantFiled: July 16, 2020Date of Patent: December 15, 2020Assignee: Apple Inc.Inventors: Fahmy Mohammed Eid, Jerome Casters

Patent number: 9588157Abstract: A current sense circuit for a PWM driver comprises: a PWM control circuit comprising: a first switching device arranged to receive a PWM signal from the PWM driver whose current is to be sensed; and a second switching device whose supply current is arranged to track the sensed current of the PWM driver. An ADC is operably coupled to the first and second switching device. The ADC comprises: a DAC arranged to provide a current sense to the second switching device that tracks the current passing through the PWM driver; a first comparator arranged to receive and compare an output current from the DAC and an output current from the first switching device; and a first successive approximation register arranged to receive an output from the comparator and provide: a first output to the ADC; and a second output that provides a representation of the sensed current.Type: GrantFiled: November 26, 2014Date of Patent: March 7, 2017Assignee: NXP USA, Inc.Inventors: Benoit Alcouffe, Jerome Casters, Tarek Hakam, Bernard Pierre Francois Pechaud

Patent number: 9525570Abstract: Current sensing circuitry for sensing a current through a load comprises an adaptive-resistance sensor component arranged to be operably coupled in series with the load, and control logic for controlling a resistance of the adaptive-resistance sensor component. The control logic is arranged to receive a signal representative of a voltage across the adaptive-resistance sensor component, compare the received signal to a reference value that is representative of a determined voltage, and in response to the comparison control the resistance of the adaptive-resistance sensor component, such that the voltage across the adaptive-resistance sensor component substantially tracks the determined voltage value.Type: GrantFiled: January 5, 2009Date of Patent: December 20, 2016Assignee: NXP USA, Inc.Inventor: Jerome Casters

Electrostatic discharge protection circuit arrangement, electronic circuit and ESD protection method
Patent number: 9438031Abstract: An electrostatic discharge, ESD, protection circuit arrangement is connectable to a first pin and a second pin of an electronic circuit and arranged to at least partly absorb an ESD current entering the electronic circuit through at least one of the first pin or the second pin during an ESD stress event. The protection circuit arrangement comprises a first ESD protection circuit arranged to absorb a first portion of the ESD current during a first part of the ESD stress event during which first part a level of the ESD current exceeds a predetermined current threshold; and a second ESD protection circuit arranged to absorb a second portion of the ESD current, the second portion having a current level below the current threshold, at least during a second part of the ESD stress event. The second ESD protection circuit comprises a current limiting circuit arranged to limit a current through at least a portion of the second ESD protection circuit to the current threshold.Type: GrantFiled: February 29, 2012Date of Patent: September 6, 2016Assignee: Freescale Semiconductor, Inc.Inventors: Patrice Besse, Jerome Casters, Jean-Philippe Laine, Alain Salles -
Patent number: 9397690Abstract: An apparatus for sensing current of a vehicle battery employs an extended counting analog-to-digital conversion process (212) to a chopped and amplified voltage appearing across a low ohmic shunt resistor (203) placed between the negative pole of the vehicle's battery and the chassis ground of the vehicle. Gain adjustment control of a programmable gain amplifier (209) by matching the gain to the dynamic range of the ADC (212) permits a high dynamic signal sensing.Type: GrantFiled: March 21, 2013Date of Patent: July 19, 2016Assignee: Freescale Semiconductor, Inc.Inventors: Jean Lasseuguette, Jérôme Casters, Stéphane Ollitrault, Thierry Robin, Olivier Tico
