BMA400 Low current consumption with SPI

[Catherine]

I would like to ask if it is better to configure the interrupt pins of the BMA400 as Push-Pull active low or active high with regard to the current consumption?

Active high doesn’t need an additional Pull-Up resistor. But the current consumption is higher when it will be activated.

Active low needs an additional Pull-Up resistor but the current consumption while activation is less then in active high mode.

What do you think? Can you give me any advice?

Hello Catherine,

Usually, interrupt output uses push-pull mode, which does not need pull-up resistor.

Whether it is active high or active low?

Hello Catherine ,

Both high and low levels are OK.
