Outputs
The totem-pole outputs have been designed to minimize
cross-conduction current spikes while maximizing fast,
high-current rise and fall times. Current limiting can be
done externally either at the outputs or at the common
V
CC
pin. The output diodes included have slow recovery
and should be shunted with high-speed external diodes
when driving high-frequency inductive loads.
Flip/Flop
Grounding F/F Enable activates the internal flip-flop to
alternate the two outputs. With pin 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 least 200nsec. must be pro-
vided to allow the flip/flop to change states. Note that the
circuit logic is configured such that the òOFFó state is
defined as the outputs low.
Digital Inputs
With both an inverting and non-inverting input available,
either active-high or active-low signals may be accepted.
These are true TTL compatible inputsDthe threshold is
approximately 1.2V with no hysteresis; and external pull-
up resistors are not required.
Inhibit Circuit
Although it may have other uses, this circuit is included to
eliminate the need for deadband control when driving rel-
atively 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
INHIBIT REF which can be set from 0.5 to 3.5 V. When this
circuit is not used, ground INHIBIT REF and leave INHIB-
IT A&B open.
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 required 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.
Supply Voltage
With an internal 5V regulator, this circuit is optimized for
use with a 7 to 40V supply, however, with some slight
response 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
CC
. When combined with a CS384X
PWM, the Driver Bias switch can be used to supply V
IN
to
the CS3706. V
IN
switching should be fast as undefined
operation of the outputs may occur with V
IN
less than 5V.
Thermal Considerations
Should the chip temperature reach approximately 155C, a
parallel, non-inverting input is activated driving both out-
puts to the low state.
