The UJA1079A core System Basis Chip (SBC) replaces the basic discrete components commonly found in Electronic Control Units (ECU) with a LIN transceiver, combined with a 250 mA voltage regulator for supplying a microcontroller; extendable with external PNP transistor for active power distribution. The UJA1079A supports the networking applications used to control power and sensor peripherals by using the LIN interface as a local sub-bus. The UJA1079A is designed to be used in combination with a microcontroller. The SBC ensures that the microcontroller always starts up in a controlled manner.
