Triple Antenna Supply | E522.44

This device is a triple phantom power supply for antennas in automotive environments. The device features an I²C interface for configuration and diagnosis. Protection is offered against short to ground, short to battery, thermal overstress, reverse voltage and reverse current. The output voltages and output currents are monitored by a 10 bit ADC via the I²C interface. Channel specific overcurrent and open load limits are configurable. The output voltages can be programmed via external voltage dividers in a range from 3V to 40V. Continous output even at low voltage supply condition is provided by switch mode. Up to four devices can be connected to one I²C bus. Four predefined I²C addresses are selectable by pin programming. Thermal management flexibility is provided by an optional external pnp transistor for pre-regulation of the input voltage. A fault indication pin is provided to signal error states.
