DESCRIPTION
APPLICATION INFORMATION
Output of the push-pull gate driver. Output capability
of 1.5A peak.
Connect directly to analog ground.
Connect directly to power ground.
Current sense input to the PWM comparator (CM
control). There is a 50ns leading edge blanking on
this pin. Using separate dedicated comparators, if
CS exceeds 0.5V the outputs will go into cycle by
cycle current limit. If CS exceeds 0.6V the outputs
will be disabled and a soft-start commenced.
An external capacitor and an internal 10uA current
source, set the soft-start ramp. The controller will
enter a low power state if the SS pin is below the
shutdown threshold of 0.45V
An external resistor sets the overlap time or dead
time for the push-pull outputs. A resistor connected
between TIME and GND produces overlap. A
resistor connected between TIME and REF produces
dead time.
An external resistor sets the oscillator frequency.
An external divider from the power converter source
sets the shutdown levels. Threshold of operation
equals 2.5V. Hysteresis is set by a switched internal
current source (20μA).
