Cautions on use
BU3056FV
·BU3056FV must be basically mounted on the board. (If it is not circuit board mounting, it can't sometimes get a
character fully.)
·Capacitors 0.1uF need to be placed between 1PIN(VDD0) and 2PIN(VSS0), 4PIN(AVDD) and 5PIN(AVSS),
13PIN(VDD) and 12PIN(VSS).
·It is effective as an EMI countermeasure when the capacitor (less than 1
) which puts ferrite beads in the
starting point of the power supply supplied to the BU3056FV by a circuit board and which makes the power
supply-GND space have a requested high frequency as to the bypass is inserted.
·For ICs with more than one power supply, it is possible that rush current may flow instantaneously due to the internal
powering sequence and delays. Therefore, give special consideration to power coupling capacitance, power wiring,
width of ground wiring, and routing of wiring.
