The AS8220A is a high-speed automotive transceiver for fault tolerant and high speed applications, operating as the bi-directional interface between a generic communication controller and the twisted pair copper wires. The device enables two-way communication with the microcontroller with full mode handling, including the low-power modes.

The transmission rates up to 10Mbps as well as the implemented Bus Guardian interface enables this transceiver the usage in fault tolerant and hard real-time applications in the stringent automotive environment. An extended diagnostic interface, offers advanced bus-failure detection capabilities with the intelligent combination of bus-current measurement and logical comparators.

A thermal sensor circuit with an integral shutdown mechanism prevents damage to the device in extreme temperature conditions. The symmetrical transient control for the high- and low-side driver for both the bus-minus and bus-plus line allows an ideal balance of communications over different network topologies, with excellent EMC performance.

The product is available in SSOP14 package.
