NOTES
1) Ceramic Capacitors C1 and C2 must be placed very close to the IC;
2) R1 and R2 set the anticipation time by partitioning the V
3) R3 is a pull-up resistor;
4) R5 limits the current flowing through diode D2 when Freewheeling drain voltage is high;
5) D1 could be necessary to protect INHIBIT pin from negative voltages.
6) D2 could be necessary to protect INHIBIT pin from voltages higher than V
7) SGLGND layout trace must not include OUTGATE current paths.
