1. Description
ATA6620N is a fully integrated LIN transceiver, designed according to the LIN specifi-
cation 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. ATA6620N 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; V
Supply Voltage up to 40V
Operating Voltage V
Typically 10 µA Supply Current During Sleep Mode
Typically 40 µA Supply Current in Silent Mode
Linear Low-drop Voltage Regulator:
