  • Patent number: 10560282
    Abstract: Two CAN bus transceivers utilized in a single integrated circuit package with the CAN bus connections between the two transceivers being inverted. Thus, one transceiver is connected to the CAN bus high and low lines while the other transceiver is connected to the CAN bus low and high lines. Both transceivers power up in a standby condition and each transceiver is monitoring for wake up signals on the CAN bus. The transceiver that is correctly connected to the CAN bus detects wake up signals. When the wake up signals are detected at that transceiver, that transceiver is brought to full operating state and the other transceiver is placed in a full standby condition. Additional input resistance is provided with each transceiver to maintain the proper input resistance for the integrated circuit.

  • Publication number: 20190131967
    Abstract: A driver includes an open drain output transistor, a capacitor, a first current source, and first and second transistors. Upon assertion of a transmit signal to turn on the first transistor, a controller asserts a second control signal to turn on the second transistor responsive to a voltage of the capacitor being less than a threshold voltage of the open drain output transistor to thereby increase the gate voltage for the open drain output transistor at a first time rate. The controller deasserts the second control signal to turn off the second transistor responsive to the capacitor voltage exceeding the threshold voltage. Responsive to the capacitor's voltage exceeding the threshold, the first current source charges the capacitor to further increase the gate voltage at a second time rate that is smaller than the first time rate.

  • Publication number: 20150352949
    Abstract: A utility vehicle (2) comprises a plurality of ground engaging members (6, 8) and a frame (4) supported by the plurality of ground engaging members. The utility vehicle includes a front seating area (24) and a rear seating area (26). A rear cargo bed (20) is reconfigurable from a configuration where it is rearward of the rear seating area to a second configuration where it includes the rear seating area space. The vehicle includes a transmission (254) having a final drive portion (258) and a plurality of transmission shafts (672, 690, 702) housed in a common housing (650), the final drive portion being forward of an end of the plurality of transmission shafts. The vehicle also includes a front suspension (72) and a rear suspension (74).

  • Patent number: 8742845
    Abstract: Various embodiments of an amplifier circuit are provided. In one embodiment, the amplifier circuit includes an input differential circuitry configured to convert a pair of input differential voltage signals to a pair of differential current signals. The amplifier circuit includes a cascode circuitry operable to mirror the pair of differential current signals received from the first output terminal and the second output terminal to an output terminal of the first cascode transistor and an output terminal of the second cascode transistor. The amplifier circuit includes a current control circuit operable to divert an amount of bias current to reduce a current through the cascode circuitry, to thereby reduce a load of the amplifier circuit, the reduction in the load of the amplifier circuit allowing a reduction in current through the input differential circuitry for maintaining a predetermined bandwidth of the amplifier circuit.
