Abstract
The present disclosure provides a system and method for soft start scheme to control inrush current for VCONN in USB-C interface. The system includes: a serial shift register having flip-flops and adapted to obtain clock with programmable clock divider, frequency of clock changes dynamically by programming programmable clock divider; a resistor DAC unit configured to increment voltage in step-wise manner; a pass gate switch comprising NMOS gate switch and a PMOS gate switch connected in parallel and operatively coupled to the resistor DAC unit and configured to control an input voltage to a VCONN charge pump, said input voltage being in incremental steps such that the VCONN charge pump pumps an output voltage; and a VCONN switch gate operatively coupled to the VCONN charge pump and configured to supply the output voltage in controlled, incremental steps, such that the output voltage is ramped slowly to control the inrush current.
