ATA6629集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

描述 Description

ATA6629/ATA6631 is a fully integrated LIN transceiver, designed according to the LIN specification 2.0, 2.1 and SAEJ2602-2, 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 powerful, slave nodes in LIN Bus systems.
