The combination of voltage regulator and bus transceiver makes it possible to develop simple, but powerful, slave nodes in LIN Bus systems. ATA6620N is designed to handle the low-speed data communication in vehicles for example, in convenience electronics . Improved slope control at the LIN driver ensures secure data communication up to 20 kBaud with an RC oscillator for the protocol handling. The bus output is designed to withstand high voltage. Sleep mode voltage regulator switched off and Silent mode communication off VCC voltage on guarantee minimized current consumption.
