Appendix A: TVSP Boot Configuration Settings

 TVSP Setting Figure A-1 TVSP Setting

The TVSP pin is a mufti-function pin, but for boot process, RTVSP is the resistor determining the boot behavior. The pin hardware connection is shown in Figure 5-1. For more details, see the RTVSP Configuration Settings in the device-specific data sheet.

At power on, the resistance between the TVSP pin and PGND determines the boot method, USB PD port I2C addresses and I2C logic thresholds. During device initialization and boot, typically within 4 seconds after power on, VIN must be above 7.6V to ensure proper bias of the TVSP pin to 5.5V. Once boot is complete the device can operate over the full VIN range.
