Note 1: Values beyond which damage may occur. All voltages
are with respect to GND. All currents are positive into
the specified terminal. Consult Unitrode databook for
information regarding thermal specifications and limita-
tions of packages.
Note 2: In normal operation V
CC
is powered through a current
limiting resistor. Absolute maximum of 12V applies
when V
CC
is driven from a low impedance source such
that I
CC
does not exceed 30mA (which includes gate
drive current requirement). The resistor should be
sized so that the V
CC
voltage, under operating condi-
tions is below 12V but above the turn off threshold.
