Note 2
Notes 1. This value only indicates the absolute maximum ratings when applying voltage to the VL1, VL2, VL3,
and V
L4 pins; it does not mean that applying voltage to these pins is recommended. When using
the internal voltage boosting method or capacitance split method, connect these pins to VSS via a
capacitor (0.47
μ F ± 30%) and connect a capacitor (0.47 μ F ± 30%) between the CAPL and CAPH
pins.
2. Must be 6.5 V or lower.
Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge
of suffering physical damage, and therefore the product must be used under conditions that ensure that
the absolute maximum ratings are not exceeded.
