DESCRIPTION

The IC interfaces between a μC and a Local Interconnect Network (LIN) bus-line, mainly in automotive sub bus applications. When pin EN is at High level (VDD), a digital input signal at pin TxD is transferred to the fully protected low side driver on pin BUS. The voltage level on pin BUS is detected by a comparator with a threshold of nominally 50 of the battery supply VS. After passing a debounce filter it is valid on pin RxD as a digital signal referenced to the digital supply voltage VDD.
