Note) *1: Absolute Maximum Ratings is values which must not be exceeded to guarantee device reliability and life,
and when using a device in excess even a moment, it may immediately cause damage to device or may
significantly deteriorate its reliability.
*2: A value based on the following implementation conditions:
Board Layer: 4 layers (FR-4), Board Size: 136 [mm] × 85 [mm], Board Copper Foil Thickness: 35 [m],
Wiring Density: 379%, Exposed stage: soldering on the board
Through Hole for heat radiation: 25 (5×5) holes from a point just below the exposed stage to the inner layer (VSS)
and B layer.
*3: A value based on the following implementation conditions:
Board Layer: 2 layers (FR-4), Board Size: 136 [mm] × 85 [mm], Board Copper Foil Thickness: 35 [m],
Wiring Density: 187%, Exposed stage: soldering on the board
Through Hole for heat radiation: 25 (5×5) holes from a point just below the exposed stage to B layer.
*4: 1 layer board, Copper Foil Thickness: 35 [m], Wiring Density: 80%, Board Size: 114.3 [mm] × 76.2 [mm]
