  • System and method for monitoring analog front-end (AFE) circuitry of an inductive position sensor
    Patent number: 11313702
    Abstract: A system and method for monitoring analog front-end (AFE) circuitry of an inductive position sensor. A redundant AFE channel is provided and alternatively utilized with a sine AFE channel or a cosine AFE channel of the AFE circuitry to obtain a voltage difference that may result in a detection angle error at the electronic control unit (ECU) of the inductive position sensor.
    Type: Grant

  • Source driver current fold-back protection
    Patent number: 8482894
    Abstract: A load current is limited to a safe level with a current protection logic circuit within a first selected interval after detection of a fault condition. The current protection logic circuit returns the load current to a normal level within a second selected interval after correction of the fault condition, wherein said safe level is less than one half of the normal level. The current protection logic circuit is a feature of a high side driver comprising at least two source drivers, each source driver being configured to switch an electrical load to a common power supply, and comprising a respective current protection logic circuit.
