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. Dual 12V gate +drive allows high power applications to either share safe operating area across +parallel MOSFETs or support a 2-stage start-up that first charges the load +capacitance followed by enabling a low on-resistance path to the load. The +LTC4282 is well suited to high power applications because the precise monitoring +capability and accurate current limiting reduce the extremes in which both loads +and power supplies must safely operate.
