ATA6621 - ATMEL Corporation

ATA6621 LIN Transceiver

The ATA6621 is a fully integrated LIN transceiver, complying 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 regula.
