DESCRIPTION
There is also a cable resistance compensation feature that allows users to adjust the output voltage to compensate for the voltage drop due to cable resistance. An OVP function protects the IC itself and its downstream system against input voltage surges. With this OVP function, the IC can stand off input voltage as high as 42V, making it an ideal solution for industrial applications such as smart meters as well as automotive applications. In automotive systems, power comes from the battery, with its voltage typically ranges between 9V and 24V. Including cold crank and double battery jump-starts, the minimum input voltage may be as low as 4V and the maximum up to 36V, This makes ETA2831 ideal for the automotive application. There is also a low side current limiting USB switch in ETA2831. The current limit is internally set at 1A. Since the total output current limit of the DCDC can be externally adjusted with a resistor, this 1A USB switch provides flexible configurations for two-port USB charging system.
