Very low active current consumption
Very low standby current (typ. < 10 µA)
Wake up output by LIN-Bus transition and EN,
battery power on
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 pass-
ing a debounce filter it is valid on pin RxD as a digital signal refer-
enced to the digital supply voltage VDD.

EN also statically keeps the high side output INH active. A high to
low transition on EN as well as VDD falling under the POR thresh-
old will dynamically reset INH to high impedance. A debounced
low level on the bus-line for a certain time will set INH to high
level as well as a - power on condition - on the battery supply
