5 / 32 page 2.3 Input The IN+ and IN– inputs to the Si828x devices act as a complementary pair. If the IN– is held low, the IN+ will act as a active-high input for the driver control. Alternatively, if IN+ is held high, then the IN– can be used as an active-low input for driver control. When the IN– is used as the control signal, taking the IN+ low will hold the output driver low. IN+ VH _ IN VL HIGH LOW HIGH LOW Pull-up Hi-Z Hi-Z Pull-down Figure 2.2. Si828x Complementary Input Diagram 2.4 Output The Si8285 and Si8286 devices are different in how the driver output is presented. The Si8285 has separate pins for gate drive high (VH) and gate drive low (VL). This makes it simple for the user to use different gate resistors to control IGBT VCE rise and fall time. The Si8286 has both actions combined in the single VO pin. A weak internal pulldown resistor of about 200 kΩ is provided to ensure that the driver output defaults to low if power on the secondary side is interrupted.
