  • Patent number: 11493982
    Abstract: Systems, methods, and circuitries are provided for controlling a microcontroller (MCU) on a per-application basis. A control system includes a microcontroller unit (MCU) including a first application group and a second application group. The first application group includes at least one hardware component not associated with the second application group. The control system includes a power management integrated circuit (PMIC). The PMIC includes monitoring circuitry configured to monitor the first application group to detect a first application group fault condition and monitor the second application group to detect a second application group fault condition. Based on the monitoring, the PMIC provides a first reset signal to the first application group that does not reset the second application group or provides a second reset signal to the second application group that does not reset the first application group.

  • Patent number: 9021284
    Abstract: One embodiment of the present invention relates to a low-power micro-controller unit having both a standby micro-controller optimized for low power consumption and a main micro-controller optimized for high performance. A power supply is coupled to the main micro-controller and the standby micro-controller. The power supply provides power to one or more of the low-power, standby micro-controller and the high performance, main micro-controller by separate power supply paths, depending on system needs. The separate power supply paths allow the main micro-controller and the standby micro-controller operate independent of each other. During a low-power standby operating mode, power can be disconnected to the main micro-controller, while providing power to the standby micro-controller, thereby eliminating the leakage current associated with the large number of transistors in the main micro-controller, while still retaining the computational capabilities of the standby micro-controller.

  • Patent number: 7865294
    Abstract: The invention relates to a method for regulating the lambda value of an internal combustion engine with a catalytic converter for subsequently treating the exhaust gases of the internal combustion engine, with a binary lambda probe, which is mounted upstream from the catalytic converter and which senses the composition of the exhaust gases. According to the invention, the lambda set value is superimposed with a lean/rich amplitude. This lean/rich amplitude has an integral component and a discontinuous component leading back to the lambda set value. When a change that differs from the change in the exhaust gas composition caused by the lean/rich amplitude is detected, the coefficient of the integral component is modified and/or a discontinuous component is added to the integral component or subtracted therefrom.
