Review Layout with INA253 (current sensing)
« on: October 23, 2020, 09:08:49 am »

I made a simple layout with three INA253 (U1, U2, U3) in parallel. In the beginning I will only solder one. Eventually I will add the second and the third if everything goes well. The datasheet of INA253,

I will manufacture the PCB with 1oz and after that I will add solder over the tracks with high current. The conenctors I will use something like this,

So with only one INA253 (10 A), are the layout and the connectors acceptable? Once I add the 2nd and the 3rd INA253 I will keep the tests with 15A maximum just to measure the results and test software. The decoupling capacitors C1, C2 and C3 are well positioned too?

Best regards,

EDIT: The ground is still not connected to the connector.
