3.7 Low-Power Mode

Low-power mode helps to control the power consumption of MTCH2120. The host presets the reduced button number in low-power mode and/or a different touch measurement interval. In low-power mode, the touch measurements occur at the interval defined in Low-Power Measurement Period (LPMP) register.

By optimally configuring the buttons as Lump sensors and configuring the Lump buttons as low-power buttons, the power consumption can be reduced effectively and controlled. For more details on Lump sensors, refer to Lump.
