2.3 Default Register Settings

The TPS65033000-Q1 is tailored to program in mass production. The following features help enable this:

  • Only the VSYS/VSYS_S/PVIN_B1 input voltage and I2C pull-up voltage are required to communicate with the device through I2C.
  • The SEQ pin must be logic HIGH to enable all regulators.
  • The GPIO pin must be logic HIGH to enable Buck3 and the LDO.

This definition enables various paths to production programming as discussed in detail in the following sections.

  1. Production line programming
  2. Serializer-Deserializer (SerDes) back-channel programming
