  • Control circuit for passive braking for DC motor
    Patent number: 11108345
    Abstract: A control circuit includes a first high-side transistor coupled between a voltage supply terminal and the first terminal of a DC motor and a second high-side transistor coupled between the voltage supply terminal and the second terminal of the DC motor. The control circuit includes a first low-side transistor coupled between a ground terminal and the first terminal of the DC motor and a second low-side transistor coupled between the ground terminal and the second terminal of the DC motor. The control circuit includes a first pull-up resistor coupled between the voltage supply terminal and a gate terminal of the first low-side transistor and a second pull-up resistor coupled between the voltage supply terminal and a gate terminal of the second low-side transistor. The pull-up resistors apply bias currents to turn ON the first and second low-side transistors to provide a conductive path to brake the DC motor.

  • Differential data transceiver and method with reversed-wire immunity
    Patent number: 8218672
    Abstract: A polarity independent differential data transceiver receives a differential voltage signal and outputs a first logic state when the differential voltage signal is in a positive voltage differential range and/or when the differential voltage signal is in a corresponding negative differential voltage range. The differential data transceiver will output a second logic state in response to receiving a voltage differential signal that is in an intermediate differential voltage range near zero between the positive differential voltage range and the corresponding negative differential voltage range.
