[VCC Reduced voltage detection]

The internal control IC of the driver has a function that detects reduced voltage when VCC is supplied, to prevent

insufficient internal P-channel MOSFET gate voltage. The reduced voltage detection level is set to VCC = 15V (typ.).

When VCC  15V, an internal control voltage has not risen above the preset threshold level, so ENABLE must be set

to low in order to turn off the MOSFET.
