2.3 VBUS Start-up Delay and Current Limiting Switch

VBUS is supplied to the board through a start-up delay circuit of approximately 1 ms and a MIC2009 current-limiting switch. This reduces inrush current and provides overcurrent protection. The current limit is configured by the current-limit resistor, R202 = 330Ω. The configured current limit is 700 mA ±30%.
