7.4 Dos and Don'ts

  • Connect the LDO5V output to the DRV5V_x_x inputs for situations where an external 5V supply is not initially available or is not available the entire time PMIC is on. If the external 5V supply is always present, then DRV5V_x_x can be directly connected to remove the V5ANA-to-LDO5P0 load switch RDSON.
  • Ensure that none of the control pins are potentially floating.
  • Include 0-Ω resistors on the DRVH or BOOT pins of controllers on prototype boards, which allows for slowing the controllers if the system is unable to handle the noise generated by the large switching or if switching voltage is too large due to layout.
  • Do not connect the V5ANA power input to a different source other than PVINx. A mismatch here causes reference circuits to regulate incorrectly.
  • Do not supply the V5ANA power input before the VSYS. Reference biasing of the internal FETs may turn on the HS FET passing the input to the output until VSYS is biased.
  • Do not change the values of the reserved bits when writing I2C, this can have unexpected consequences. Expected values for each OTP are shown in the register map.
