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 VCC is powered through a current

limiting resistor. Absolute maximum of 12V applies

when VCC is driven from a low impedance source such

that ICC does not exceed 30mA (which includes gate

drive current requirement). The resistor should be

sized so that the VCC voltage, under operating condi-

tions is below 12V but above the turn off threshold.
