D1, D2: UC3611 Schottky Diodes
Transformer Coupled MOSFET Drive Circuit
CIRCUIT DESCRIPTION (cont.)
Analog Shutdown
This circuit is included to get a latched shutdown as close
to the outputs as possible, from a time standpoint. With
an internal 130mV threshold, this comparator has a
common-mode range from ground to (V
IN
– 3V). When
not used, both inputs should be grounded. The time re-
quired for this circuit to latch is inversely proportional to
the amount of overdrive but reaches a minimum of
180nsec. As with the flip-flop, an input off-time of at least
200nsec is required to reset the latch between pulses.

APPLICATIONS
Power MOSFET Drive Circuit
D1, D2; UC3611 Schottky Diodes
Power MOSFET Drive Circuit Using Negative Bias Voltage and
Level Shifting to Ground Referenced PWMs
Supply Voltage
With an internal 5V regulator, this circuit is optimized for
use with a 7 to 40V supply; however, with some slight re-
sponse time degradation, it can also be driven from 5V.
When V
IN
is low, the entire circuit is disabled and no cur-
rent is drawn from V
C
. When combined with a UC1840
PWM, the Driver Bias switch can be used to supply V
IN
to
the UC1706.
V
IN
switching should be fast as if V
C
is
high, undefined operation of the outputs may occur with
VI
N
less than 5V.
Thermal Considerations
Should the chip temperature reach approximately 155°C,
a parallel, non--inverting input is activated driving both
outputs to the low state.
