Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

APPLICATION INFORMATION
Shutdown Options
(See Block Diagram, page 2)
Since both the compensation and softstart terminals
(Pins 9 and 8) have current source pullups, either can
readily accept a pulldown signal which only has to sink a
maximum of 100 A to turn off the outputs. This is subject
to the added requirement of discharging whatever external
capacitance may be attached to these pins.
An alternate approach is the use of the shutdown circuitry
of Pin 10 which has been improved to enhance the available
shutdown options. Activating this circuit by applying a
positive signal on Pin 10 performs two functions: the PWM
latch is immediately set providing the fastest turnoff signal
to the outputs; and a 150 A current sink begins to discharge
the external softstart capacitor. If the shutdown command
is short, the PWM signal is terminated without significant
discharge of the softstart capacitor, thus, allowing, for
example, a convenient implementation of pulsebypulse
current limiting. Holding Pin 10 high for a longer duration,
however, will ultimately discharge this external capacitor,
recycling slow turnon upon release.
Pin 10 should not be left floating as noise pickup could
conceivably interrupt normal operation.
