2.7.2 On-Board Sensors

The xWRL6432AOPEVM provides access to an on-board temperature sensor (TMP112AQDRLRQ1) and four on-board current sensors (INA228AIDGST). These sensors can be controlled by the radar via I2C.

The current sensors are designed to measure the current being supplied to the various power rails of the xWRL6432AOP device. For details on the supply rails that can be measured using the current sensors, refer to Table 3-4.
