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.

► Short circuit current limitation
► Over temperature protection
► Bus-line DC voltage range – 24V to + 30V
► Receiver debounce filter
► Very low active current consumption
► Very low standby current (typ. < 10 µA)
► Wake up output by LIN-Bus transition and EN, battery power on
► – 40°C to + 125°C operating temperature
► SO 8n package

APPLICATION
► Bus interface for Local Interconnect Network (LIN) communication especially in automobile applications
