K-Line
The K-Line module is a serial link bus interface device designed to provide bi-directional half-duplex
communication interfacing. It is designed to interface between the vehicles via the special ISO K-line and meets
the ISO norm 9141 specification. The device's K line bus driver's output is protected against bus shorts.
K-Line module transforms 5.0V micro-controller logic signals to battery level logic signals and vice versa. The over
current limitation limits the current to a specified limit. In case of over-temperature on OUT1 the low-side switch
and the output stage KIO will be switched off and can only be re-activated if the temperature has decreased below
the minimum hysteresis value.
