ATA6620

1. Description

ATA6620 is a fully integrated LIN transceiver, designed according to the LIN specifica-

tion 2.0, with a low-drop voltage regulator (5V/50 mA). The combination 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 com-

munication 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.
