A5191HRT Design for Low-power Environments
■The typical HART application can draw power from the current loop. However, for some applications, this power budget can be extremely restrictive.
■For other applications, particularly handheld and/or movable HART devices, it may be undesirable to rely on the current loop for power, and the design could be powered by batteries. If this is the case, the design specifications often put a restriction on the minimum battery life and even the size − and thus capacity − of the batteries.
■In both these cases, it is desirable to limit the power consumption of each section of the device to the bare minimum. In this design note, we will cover some actions that can be undertaken to reduce power consumption of theA5191HRT.
