Sleep Mode is entered by setting the CONFIG.SLEEP_MODE_EN register field to 1. While in this mode, the device configuration is retained, but the device does not perform conversions. To enter Normal mode to perform conversions, set the CONFIG.SLEEP_MODE_EN register field to 0. After setting CONFIG.SLEEP_MODE_EN to b0, sensor activation for the first conversion will begin after 16,384÷ƒINT elapses. Refer to Clocking Architecture for more information on the device timing.
While in Sleep Mode the I2C interface is functional so that register reads and writes can be performed. Entering Sleep Mode will clear all conversion results, any error conditions, and de-assert the INTB pin.
For applications which do not require continuous conversions, returning the device to Sleep mode after completion and readback of the desired number of conversions can provide power consumption savings. Refer to the TI Applications Note Power Reduction Techniques for the LDC131x/161x for Inductive Sensing for more information.
