Short Description
The MLX8005x/3x consist of a low-drop voltage regulator 5V/3.3V/70mA combined with a Reset/Watchdog unit and a
LIN bus transceiver. The LIN transceiver is suitable for LIN bus systems conform to LIN specification revision 2.x and SAE
J2602. The watchdog times of the integrated window watchdog can be adapted on application needs via external resis-
tors. With the help of an external bipolar transistor it is possible to extend the output current of the integrated voltage
regulator. The combination of voltage regulator and bus transceiver as well as watchdog unit makes it possible to de-
velop simple, but powerful and cheap slave nodes in LIN Bus systems.
