ELECTRICAL CHARACTERISTICS (continued)
(VS = +9V to +72V, GND = 0, ON/OFF open circuit, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VS = +48V
and TA = +25°C.) (Notes 2, 3)

Note 2: All currents into device pins are positive, all currents out of device pins are negative, and all voltages are referenced to
GND, unless otherwise noted.
Note 3: All specifications are 100% tested at TA = +25°C, unless otherwise noted. Specifications over -40°C to +85°C are guaran-
teed by characterization.
Note 4: This is the delay time from a valid on condition until VGS begins rising. Valid on conditions are: the device is not in undervolt-
age lockout; ON/OFF is not driven low; and the device is not in thermal shutdown.
Note 5: This is the delay from a valid low on ON/OFF until VGS falls. Pulses on ON/OFF less than tOFF are ignored, offering glitch
immunity.
Note 6: Guaranteed by characterization, not production tested. CGATE is a capacitor from GATE to VS.
