Pin Description
HIN(U,V,W) and LIN(U,V,W) (Low side and high
side control pins, Pin 7 - 12)
These pins are positive logic and they are
responsible for the control of the integrated IGBT.
The Schmitt-trigger input thresholds of them are
such to guarantee LSTTL and CMOS compatibility
down to 3.3V controller outputs. Pull-down resistor
of about 5k is internally provided to pre-bias inputs
during supply start-up and a zener clamp is
provided for pin protection purposes. Input Schmitt-
trigger and noise filter provide beneficial noise
rejection to short input pulses.
The noise filter suppresses control pulses which are
below the filter time t_FILIN. The filter acts according to
Figure 4.
