Using one or more external N-channel pass transistors, +board supply voltage and inrush current are ramped up at an adjustable rate. An +I2C interface and onboard ADC allows for monitoring of board current, voltage, +power, energy and fault status. The device features analog foldback current +limiting and supply monitoring for applications from 2.9V to 33V.
