Hi, Thanks for your inquiry. BMA253 low power mode 2 is automatically switching between normal mode (130uA) and standby mode (62uA) according to the selected sleep time. When the sleep time is set to 25ms and the bandwidth is set to 1KHz, then the typical average current consumption becomes 66uA as shown in the datasheet. However, when you enable low-g interrupt in low power mode 2 with the low-g threshold and duration parameters that you set, BMA253 will spend more time which is the low-g duration in normal mode to take measurements to see if low-g interrupt condition is met or not. If the condition is not met, then BMA253 will enter standby mode and wait for another 25ms sleep time to expire so that it can enter normal mode again. If the condition is met, then BMA253 will generate low-g interrupt. For example, if the sleep time is still 25ms and the low-g duration is set to 200ms for about 20cm height freefall detection, then BMA253 will consume close to 130uA. This is because 25ms sleep time @62uA plus 200ms normal mode (130uA) will result in about 122uA average current which is close to 130uA. Thanks. Thanks. ... View more

Hi, Thanks for your inquiry. BMP384 is water-resistant. So its pad size of 0.27 x 0.285mm is a little larger than BMP388's 0.27 x 0.25mm. In order to replace BMP388, you can choose BMP390 which is pin-to-pin compatible with BMP388 and the pad size is also the same. BMP388, BMP384 and BMP390 share the same API code on the Github at https://github.com/BoschSensortec/BMP3-Sensor-API. BMP390 can be purchased at https://www.mouser.com/ProductDetail/Bosch-Sensortec/BMP390?qs=sGAEpiMZZMv0NwlthflBi1BC1g8rC9UGRBLSivm3tHU%3D. Thanks. ... View more
