Description
3 IN IC input. When IN is high, OUT is high.
If necessary, a capacitor (recommend 100pf) can be connected
4 OPT
from OPT to COM to filter out input noise.
5 COM Common reference pin.
IC output pin. Provide gate driving voltage for the
6 OUT
freewheeling MOSFET.
8 BST A 220nf capacitor should be connected from BST to COM.
Application circuit
There is an external small toroid transformer used to sense current and provide driving signal
for WT6002 chip.
