The NCV7428D15R2G is a System Basis Chip (SBC) integrating functions typically found in automotive electronic control units (ECUs). The NCV7428 provides and monitors the low-voltage power supply for the application microcontroller and other loads and includes a LIN transceiver. It integrates on-chip LIN transceiver interface between physical LIN bus and the LIN protocol controller. This LIN physical layer is compatible to LIN2.x and J2602 specifications. It is typically connected to the car battery through a reverse-protection diode and can be exposed to all relevant automotive disturbances (ISO7637 pulses, system ESD). The VS supplies mainly the integrated LIN transceiver. Filtering capacitors should be connected between VS and GND. During power-up of the battery supply, VS pin must reach VS_PORH level in order for the circuit to become functional - the internal state machine is initiated and the VOUT regulator is activated.
