Circuit Interruption By Thermal Sensing Patents (Class 361/103)
  • Patent number: 11196334
    Abstract: A current limiter 200 (corresponding to an example of a current detection circuit) has a comparator 210 and a variable delay unit 220. The comparator 210 switches a comparison signal OCP from a low level to a high level when the current to be monitored, which flows through an output switch, reaches a predetermined threshold value (in the present figure, when a sense voltage Vcs reaches an overcurrent detection voltage Vocp). The variable delay unit 220 measures a first time T1 from when the output switch turns on by SET=H until when the comparison signal OCP switches to the high level and delays the comparison signal OCP by a second time T2 (=K·T12) proportional to the square of the first time T1 to generate an overcurrent detection signal Sc. The variable delay unit 220 includes a first timer 223 for measuring the first time T1 and a second timer 224 for generating the overcurrent detection signal Sc by delaying the comparison signal OCP by the second time T2.

A counting circuitry driven by the comparison signal counts in a first count direction as a result of the comparison signal indicating that the current intensity exceeds the reference value. Latching circuitry coupled to the counter circuitry generates the output signal at the output node as a result of the count value of the counter circuitry reaching a limit value.

  • Patent number: 11065962
    Abstract: An inverter ECU is applied to a hybrid vehicle having an engine and a motor generator as drive power source and a motor generator control system. A drive control part generates drive signals for an inverter based on torque request to the motor generator. A temperature information acquiring part acquires an element temperature value and a cooling water temperature value as an inverter temperature value. An abnormality detection part detects whether the inverter temperature value is within a diagnosable temperature range, and performs abnormality detection for the motor generator control system when the inverter temperature value is within the diagnosable temperature range. When the inverter temperature value is not placed within the diagnosable temperature range, the energy supplied to the inverter is adjusted to move the inverter temperature value into the diagnosis allowable temperature range to correctly perform the abnormality detection.

    Abstract: A lighting device, such a light-emitting diode (LED) light source, may operate in an interim operable state to avoid and/or prevent undesirable characteristics in the light emitted by the lighting device (e.g., strobing and/or flickering of a brightness of the light and/or shifting or change of a color of the light). When operating in a normal state, the control circuit may determine if a measured value of a first operational characteristic (e.g., a forward voltage of an emitter of the lighting device) is outside of a range and operate in the interim operable state if the measured value of the first operational characteristic is outside of the range. When operating in the interim operable state, the control circuit may adjust a drive current for the emitter in response to a measured value of a second operational characteristic (e.g., a forward voltage of a detector of the lighting device).

    Abstract: A floating input detection method and circuits. A method for detecting a floating signal input terminal includes providing a common-mode input voltage to a first amplifier coupled to the signal input terminal, and providing an output signal generated by the first amplifier to: a non-inverting input of a second amplifier coupled to the signal input terminal, an inverting input of the second amplifier, coarse detection circuitry, and fine float detection circuitry.

  • Patent number: 10707675
    Abstract: An electric-wire protection device includes a voltage adjustment unit that adjusts the voltage to a load, and a controller that includes a temperature calculation unit that calculates temperature information on an electric wire from a value of current, and makes the voltage adjustment unit into a shut-off state based on the temperature information. The temperature information is calculated from an amount of temperature changes based on the current value and a predetermined initial value. The controller shifts into a sleep state when a sleep condition is satisfied that includes a condition that the temperature information is lower than the initial value. The initial value when the controller returns from the sleep state is based on a convergence value of temperature in conducting energization on the electric wire at a maximum value of steady-state current.

  • Patent number: 10678278
    Abstract: Controlling an activation status of a proportional-integral-derivative (PID) controller for an information handling system cooling system, such as the on/off status of the PID controller, can reduce power consumption and processing and memory requirements for such a system. A decrease in resource consumption can be realized by deactivating the PID controller during certain periods and activating the PID controller during others. For example, the PID controller can be deactivated when a temperature of a system component falls below a threshold temperature and activated when the temperature of the system component rises above the threshold temperature.
