Abstract: A Local Interconnect Network (LIN) driver circuit employs a charging/discharging current applied to the gate of a driver transistor coupled to an LIN bus. The charging current includes a constant charging current and an additional soft charging current, whereas the discharging current includes a constant discharging current and an additional soft discharging current. As a result of the soft charge/discharge components, there is a significant reduction in electromagnetic emission on the LIN bus.
