Part Number: TPS2H160-Q1

Hi Sir,

My customer has some question about the GND network?

1. In the datasheet,  what kind of the design condition to select the layout for without the GND network(figure.44) or  with the GND network(figure.45)?

2. the EVM user guide, what is the purpose about D1 and R7?

    Henry,

    For #1, this is actually related to #2. If you are using the diode/resistor as described in #2, follow the "with ground network" recomendation.

    For the purpose of the network, it is for reverse current. Please refer to 8.3.7.4 Reverse-Current Protection in the datasheet.

    Best Regards,
    Tim
