General Description
   The E522.40B is a dual phantom supply with I2C interface for antennas in automotive environments. It affords protection of the antenna lines against ESD, short to ground and battery, as well as protection against thermal over-stress of the IC.

FEATUREs
◾ Automotive compatible input voltage range from
   3.3V to 40V including load dump transients.
◾ Resistor programmable output voltages from 3.3V
   to V
   BAT with integrated soft start.
◾ Up to 200mA load current with digitally
   programmable overcurrent- and open load levels.
◾ Protection against supply over/under voltage,
   overtemperature and overcurrent with
   open-drain error flag.
◾ Output for optional external bipolar NPN-transistor
   to reduce power dissipation.
◾ Integrated I2C interface allows for programming of
   protection limits and voltage and current monitoring.
◾ Control interface with digital comparator for
   additional functions.
◾ Fast 8bit ADC samples relevant system voltages
   and currents.

APPLICATIONs
◾ Automotive Antenna Modules
◾ Navigation and Radio Units
◾ General Voltage Regulator Applications
