General Description
single-wire transceiver AMIS-30600 monolithic integrated circuit SO-8 package. works interface between protocol controller physical bus. AMIS-30600 especially suitable drive line systems automotive industrial applications. Further used standard ISO9141 systems. order reduce current consumption AMIS-30600 offers stand-by mode. wake-up caused message sets output pulls INH-output high until device switched normal operation mode. transceiver implemented I2T-100 technology enabling both high voltage analogue circuitry digital functionality co-exist same chip. AMIS-30600 provides ultra-safe solution today's automotive In-Vehicle Networking requirements providing unlimited short circuit protection event fault condition.

Application Information

fail safe reasons AMIS-30600 already internal pull resistor implemented. achieve required timings dominant recessive transition signal additional external termination resistor required. recommended place this resistor master node. avoid reverse currents from line into battery supply line case unpowered node, recommended place diode series external pull small systems (low capacitance) performance system supported additional capacitor least master node (see figure Typical application diagram). capacitor 10µF supply voltage input buffers input voltage. combination with required reverse polarity diode this prevents device from detecting power down conditions case negative transients supply line.
order reduce current consumption AMIS-30600 offers sleep operation mode. This mode selected switching enable input (see figure state diagram). sleep mode voltage regulator controlled output order minimize current consumption whole application. wake-up caused message communication automatically enables voltage regulator switching output high. parallel, wake-up indicated setting output low. When entering normal mode this wake-up flag reset output released transmit data. case voltage regulator control input connected output microcontroller active respectively, AMIS-30600 normal operation mode without wake-up communication bus.
