1.8V_Output_LDO

  • Need a revision of the TVS diode and the terminal block

    • image-20240909-033255.pngImage Added Essentially a power protection circuit. Saves designer from incorrect connection to connector.

      • Schottky diode blocks reverse current if battery connected opposite way

      • TVS diode prevents transient voltage spikes and clamps if voltage of 6.4V is detected

        • Switch TVS diode for a diode which clamps at about 4V

  • Check the choice of LED

    • image-20240909-034118.pngImage AddedGood work showing calculations with notes

  • IC is good (both footprint and schematic symbol)

  • LEFT REMAINING COMMENTS BELOW FOR POWER.SCHDOC

ICM-20948

IC_9DOF_IMU_W24

ICM20948 - 9DOFIMU

  • Check the footprint of the IMU since there is a slight different comparing to the rev 1 footprint

  • Need to add the test point/debugging feature later

  • Checking if we need to use the AUX/DA feature since the rev1 does not use it too

TXB0104PWR

TXB0104PWR

TXB0104PWR 4-bit directional voltage-level translator

  • The purpose of this one is changing the 3.3V from the MCU to 1.8V to suit in the IMU

  • Need to use 2 since there are not enough pins to change from only one 4-bit? Maybe find the another one with enough pins if we can?

  • Maybe need a test point just in case there is something wrong with this one

<Rayyan Mahmood>)

  •  Add a second LED for 1.8V outimage-20240909-040123.pngImage Added
  •  image-20240909-040141.pngImage Added Change the colour of this title to match the colour of “GND”, “3V3”, etc.
  •  Add test points for 1.8V and 3.3V and a GND test point as well.
    •  Look at the 48-17V buck schematic and see which TPs were used for the power and GND and use the exact same ones here
  •  

GPS_Module.SchDoc (<Rayyan Mahmood>)

  •  It is up to the designer’s discretion as to what should be reviewed for each schematic sheet
