Description ATA6620 is a fully integrated LIN transceiver, designed according to the LIN specification 2.0, with a low-drop voltage regulator (5V/50 m A). The bination of voltage regulator and bus transceiver makes it possible to develop simple, but powerful, slave nodes in LIN Bus systems. ATA6620 is designed to handle the low-speed data munication in vehicles (for example, in convenience electronics). Improved slope control at the LIN driver ensures secure data munication up to 20 k Baud 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 (munication off; VCC voltage on) guarantee minimized current consumption. Rev. 4850A- AUTO- 02/05 Figure 1-1.
