Publication number: 20230185322Abstract: Monitoring for an over-voltage condition based on a regulated voltage is disclosed. A first terminal of a voltage regulator receives a first voltage which is based on a regulated voltage input to a controller. A second terminal of the voltage regulator receives a second voltage indicative of the voltage input to the controller. A determination is made whether the first voltage exceeds the first voltage reference for a first time window and the controller is reset based on the determination that the first voltage exceeds the first voltage reference. A determination is also made whether the second voltage exceeds the second voltage reference for the second time window and the voltage regulator is powered down on based on the determination that the second voltage exceeds the second voltage reference.Type: ApplicationFiled: December 7, 2022Publication date: June 15, 2023Inventors: Loic Hureau, Maxime Clairet, Alaa Eldin Y.

Patent number: 11502506Abstract: An apparatus is disclosed that in one embodiment includes a circuit configured to selectively activate a transistor. The circuit is further configured to assert a signal when the circuit detects an electrical short between terminals of the transistor or when the circuit detects the transistor does not conduct current while the transistor is activated by the circuit. The circuit is further configured to output another signal, which is set to a first state or a second state. The other signal is set to the first state when the circuit detects the electrical short. The other signal is set to the second state when the circuit detects the transistor does not conduct current while activated.Type: GrantFiled: September 15, 2020Date of Patent: November 15, 2022Assignee: NXP USA, Inc.Inventors: Jean-Christophe Patrick Rince, Jean-Philippe Meunier, Erik Santiago, Antoine Fabien Dubois, Maxime Clairet

Patent number: 11500403Abstract: A system-on-a-chip (SoC) is designed to operate within optimal voltage and frequency ranges. If an SoC is provided power outside of the optimal voltage range, the SoC can be placed in a high-stress state, exposing the chip to a security attack. Embodiments of the present systems and method limit the minimum and maximum voltage supplied to an SoC from a power management integrated circuit (PMIC). Embodiments can also track a number of requests to provide power outside of the optimal range and can signal a warning of repeated attempts to take an SoC outside of the SoC's optimal range, which may be indicative of a malicious attack on the system.Type: GrantFiled: March 17, 2021Date of Patent: November 15, 2022Assignee: NXP USA, INC.Inventors: Jean-Philippe Meunier, Maxime Clairet, Alaa Eldin Y El Sherif, Pierre Turpin
