Preliminary Technical Data

Auto Sleep Mode

Additional power can be saved if the ADXL346 automatically

switches to sleep mode during periods of inactivity. To enable

this feature, set the THRESH_INACT register (Address 0x25)

and the TIME_INACT register (Address 0x26) each to a value

that signifies inactivity (the appropriate value depends on the

application), and then set the AUTO_SLEEP bit and the link bit in

the POWER_CTL register (Address 0x2D). Current consumption

at the sub-8 Hz data rates used in this mode is typically 35 µA

for a VS of 2.5 V.

Standby Mode

For even lower power operation, standby mode can be used.

In standby mode, current consumption is reduced to 1 µA

(typical). In this mode, no measurements are made. Standby mode

is entered by clearing the measure bit (Bit 3) in the

POWER_CTL register (Address 0x2D). Placing the device into

standby mode preserves the contents of FIFO.
