ELECTRICAL CHARACTERISTICS The ● denotes specifications which apply over the full operating
temperature range, unless otherwise noted specifications are at T A = 25 ° C, V IN = 12V, CTL and GND = 0V. Current into a pin is positive
and current out of a pin is negative. All voltages are referenced to GND, unless otherwise specified.
