ATA6625

1. Description

ATA6623/ATA6625 is a fully integrated LIN transceiver, designed according to the LIN

specification 2.0, with a low-drop voltage regulator (3.3V/5V/50 mA). The combination

of voltage regulator and bus transceiver makes it possible to develop simple, but pow-

erful, slave nodes in LIN Bus systems. ATA6623/ATA6625 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; V_CCvoltage on) guarantee minimized current consumption.
