Dual, 1.5A Totem Pole Outputs
40nsec Rise and Fall into 1000pF
Parallel or Push-Pull Operation
Single-Ended to Push-Pull Conversion
The UC1706 family of output drivers are made with a high-speed
Schottky process to interface between low-level control functions and
high-power switching devices - particularly power MOSFET's. These de-
vices implement three generalized functions as outlined below.
First: They accept a single-ended, low-current digital input of either polar-
ity and process it to activate a pair of high-current, totem pole outputs
which can source or sink up to 1.5A each.
High-Speed, Power MOSFET
Compatible
Second: They provide an optional single-ended to push-pull conversion
through the use of an internal flip-flop driven by double-pulse-
suppression logic. With the flip-flop disabled, the outputs work in parallel
for 3.0A capability.

able in surface mount Q and L packages.

when driving high-frequency inductive loads.
Inhibit Circuit
Although it may have other uses, this circuit is included to
Flip/Flop
eliminate the need for deadband control when driving
relatively slow bipolar power transistors. A diode from
each inhibit input to the opposite power switch collector
will keep one output from turning-on until the other has
turned-off. The threshold is determined by the voltage on
pin 15 which can be set from 0.5 to 3.5V. When this cir-
cuit is not used, ground pin 15 and leave 1 and 16 open.
Grounding pin 7 activates the internal flip-flop to alter-
nate the two outputs. With pin 7 open, the two outputs
operate simultaneously and can be paralleled for higher
current operation. Since the flip-flop is triggered by the
digital input, an off-time of at last 200nsec must be pro-
vided to allow the flip/flop to change states. Note that the
circuit logic is configured such that the “OFF” state is de-
fined as the outputs low.

use with a 7 to 40V supply; however, with some slight re-
sponse time degradation, it can also be driven from 5V.
When VIN is low, the entire circuit is disabled and no cur-
rent is drawn from VC. When combined with a UC1840
PWM, the Driver Bias switch can be used to supply VIN to
the UC1706. VIN switching should be fast as if VC is
high, undefined operation of the outputs may occur with
VIN less than 5V.
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 (VIN – 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.
Thermal Considerations
Should the chip temperature reach approximately 155°C,
a parallel, non--inverting input is activated driving both
outputs to the low state.
Supply Voltage
With an internal 5V regulator, this circuit is optimized for
