7.4.2 Sleep Mode

The TMAG5173-Q1 supports an ultra-low power sleep mode where it retains the critical user configuration settings. In this mode the device doesn't retain the conversion result data. A microcontroller can wake up the device from sleep mode to standby mode through I2C communications or the INT pin. The time it takes for the device to go to standby mode from sleep mode is denoted by Tstart_sleep.
