ATA6621 Description
The ATA6621 is a fully integrated LIN transceiver, plying with the LIN specification, and with a low-drop voltage regulator for 5V/50 mA output and a window watchdog adjustable via an external resistor. 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.
