Description

TI Design TIDEP-0091 highlights strategies for power optimization of IWR14xx 76- to 81-GHz mmWave sensors in tank level-probing applications, displacement sensors, 4- to 20-mA sensors, and other low-power applications for detecting range with high accuracy in a minimal power envelope. In these applications, the system often operates on a low-voltage data line that provides less power than the operational power consumption. Duty cycling is critical to reducing the average power to meet the power input restrictions. Power optimization is achieved through MSP432 external duty cycling the IWR14xx device for periodic sensing. Additionally, this TI Design provides a sample configuration for single-dimensional range detection.
