Pin functions (continued)
CC
Gate driver output. The totem pole output stage is able to drive Power
MOSFETs and IGBTs. It is capable of 600 mA source current and 800 mA
sink current (minimum values). The high-level voltage of this pin is clamped
at about 12 V to avoid excessive gate voltages in case the pin is supplied with
a high V
Supply voltage of both the signal part of the IC and the gate driver.
Sometimes a small bypass capacitor (0.1 µF typ.) to GND may be useful in
order to get a clean bias voltage for the signal part of the IC. The voltage on
the pin is internally clamped at 22.5 V min. to protect the internal circuits from
excessive supply voltages.
