Abstract: A bus driving device includes at least three high-side output drivers and at least three low-side output drivers. A part of the high-side output drivers and a part of the low-side output drivers are alternately coupled in series, and the remains of the high-side output drivers and the low-side output drivers are alternately coupled in series. The part of the high-side output drivers and the part of the low-side output drivers receive an input digital signal and sequentially drive a first supply bus and a second supply bus based on the input digital signal, and the remains of the high-side output drivers and the low-side output drivers receive the inverted input digital signal and sequentially drive the first supply bus and the second supply bus based on the inverted input digital signal.

Abstract: A bus driver module with controlled circuit is connected to a controller area network bus for generating a high side output or a low side output, comprising a transition controlled circuit and an output driver. The transition controlled circuit comprises a first pathway controlled unit connected in parallel with a second pathway controlled unit for generating a side switching voltage. The output driver is connected in series with the transition controlled circuit and receives the side switching voltage so as to accordingly generate the output bus signal. Each of the first and second pathway controlled unit comprises a plurality of switches and can be activated depending on an input signal. By controlling the switches of the first or second pathway controlled unit to be sequentially turned on and off successively, the side switching voltage is characterized by a smooth phase transition, low common mode noise and better EMI performances.
