Caution for implementing LV5681P to a system board
In HZIP15J, the package used in this IC, there are several metal exposure other than the connection pins and heat-sinks as shown in
the following diagrams. In the diagrams, the electric potential of 2 and 3 are the same as Pin15 and Pin1, respectively. 2 (=Pin15) is
EXT pin and 3 (=Pin1) is ILM output (regulator). When the IC is implemented to the system, make sure that no attachment clamp
touches the exposed Pin1/ Pin15. When the exposed Pin1/ Pin15 touch the attachment clamp (same electrical potential as GND), ILM
output or VCC enter the same state as time when GND was shorted. The electric potential of the exposed metal connected to heat-sinks
1 is the same as that of sub board of the IC (GND). Therefore, even if the exposed metal and GND of the system board are adjacent to
each other, there should be no problem.
