Device and method for slew rate generation for LIN bus drivers

摘要

Method for generating low-emission and / or a LIN bus compliant data pulse • where the signal voltage (V) of the data signal in the rising data edge up to a first point in time (1) at which the signal voltage (V) is below a first voltage value, which at des 0.282 times the operating voltage (V), with a first rate of rise, the first slew rate, and increases after the first voltage value is exceeded with a second rate of rise and • where the signal voltage (V) of the data signal in the falling data edge up to a second point in time (4) at which the signal voltage (V) again falls below a second voltage value, which is also 0.282 times the operating voltage (V), at a first rate of decrease, the third slew rate, and after it falls below it of the second voltage value falls with a second rate of fall and • wherein the second rate of rise is higher t than the first rate of rise and the second rate of fall is lower than the first rate of fall.
