SLUSBX9I March 2014 – July 2019 TPS23861
Inrush-current limiting is provided by the TPS23861 according to the curve in Figure 57. When the port is first powered on, the TSTART timer is started. While the TSTART timer is counting, the port current is limited to IINRUSH, as shown in Figure 57. If at the end of tSTART period the current is still limiting at IINRUSH, the port is powered off and the STRTn bit in the Start/ILIM Event Register is set with the option of asserting an interrupt.
