In this QFN20 package, the voltage regulator is able to source 50 mA at VS = 18V even at an ambient temperature of 105°C. The output current of the regulator can be boosted by using an external NPN transistor. This combination makes it possible to develop simple, but powerful and cheap, slave nodes in LIN bus systems. ATA6621N 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. The bus output is capable of withstanding 60V. Sleep mode and Silent mode guarantee a very low current consumption.
