_______________________________________________________________________________________ 3
Note 1: 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 2: All specifications are 100% tested at T
A
= +25癈, unless otherwise noted. Specifications over -40癈 to +85癈 are guaran-
teed by characterization.
Note 3: This is the delay time from a valid on condition until V
GS
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 4: This is the delay from a valid low on ON/OFF until V
GS
falls. Pulses on ON/OFF less than t
OFF
are ignored, offering glitch
immunity.
Note 5: Guaranteed by characterization, not production tested. C
GATE
is a capacitor from GATE to V
S
.
