3.4 Chip Select Digital Input (CS)
This input (CS) is a CMOS, Schmitt-triggered input that
places the part into a low-power mode of operation.
3.5 Exposed Thermal Pad (EP)
There is an internal connection between the exposed
thermal pad (EP) and the V
SS
pin; they must be
connected to the same potential on the printed circuit
board (PCB).
This pad can be connected to a PCB ground plane to
provide a larger heat sink. This improves the package
thermal resistance (
