ORDER INFORMATION
The main gate drive output (OUT1) is controlled by the
pulse width modulator. The second output (OUT2) is in-
tended to activate an auxiliary switch during the off time
of the main switch, except that between each transition
there is deadtime where both switches are off, pro-
grammed by a single external resistor. This design offers
two options for OUT2, normal and inverted. In the -1 and
-2 versions, OUT2 is normal and can be used to drive
PMOS FETs. In the -3 and -4 versions, OUT2 is inverted
and can be used to drive NMOS FETs. In all versions,
both the main and auxiliary switches are held off prior to
startup and when the PWM command goes to zero duty
cycle. During fault conditions, OUT1 is held off while
OUT2 operates at maximum duty cycle with a guaran-
teed off time equal to the sum of the two deadtimes.
Undervoltage lockout monitors supply voltage (VDD), the
precision reference (REF), input line voltage (LINE), and
the shutdown comparator (SHTDWN).
these four have sensed a fault condition, recovery to full
operation is initiated with a soft start. VDD thresholds, on
and off, are 15V and 8.5V for the -2 and -4 versions, 9V
and 8.5V for the -1 and -3 versions.
