What is the surge/inrush current of BMA253 before it stabilizes?
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 .
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.
