    BMA253 Inrush Current

    Hi

    What is the surge or inrush current as soon as the accelerometer (BMA253) is turned on before it stabilizes?

    Thanks

    Re: BMA253 Inrush Current

    1. There is inrush current during powering up of the BMA253, and the current depends on the system characterization. For example, inrush current(~1.1mA, last for 800us) of BMA253 can be seen during power up of VDD at 3.3V, with 100nF decoupling capacitor between VDD & GND  .
    1. No inrush current when switch BMA253 from suspend mode to normal mode, the current consumption jumps to directly to a level(~150uA) upon enabling normal mode.
