Using an external N-channel pass transistor, board supply voltage and inrush current are ramped up at an adjustable rate. An I2C interface and onboard ADC allow for monitoring of load current, voltage and fault status. The device features adjustable foldback current limit and a soft-start pin that sets the dI/dt of the inrush current. An I2C interface may configure the part to latch off or automatically restart after the LTC4215 detects a current limit fault. The controller has additional features to interrupt the host when a fault has occurred, notify when output power is good, detect insertion of a load card, and power-up either automatically upon insertion or wait for an I2C command to turn on. 4215 TA01b CL = 12000µF 50ms/DIV VDD 10V/DIV VOUT 10V/DIV VGPIO (POWERGOOD) 10V/DIV INRUSH CURRENT 2.5A/DIV CONTACT BOUNCE , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
