Description
1 IN1 IC input. When IN1 is high, OUT1 is high. If necessary, a capacitor (recommend 100pf) can be connected
2 OPT1 from OPT1 to COM to filter input signal noise.
3 IN2 IC input. When IN2 is high, OUT2 is high. If necessary, a capacitor (recommend 100pf) can be connected
4 OPT2 from OPT2 to COM to filter out input noise.
5 COM Common reference pin. IC output pin. Provide gate driving voltage for the rectifier
6 OUT2 MOSFET. IC output pin. Provide gate driving voltage for the
7 OUT1 freewheeling MOSFET.
8 BST A 220nf capacitor should be connected from BST to COM.
