CMOS Buffer 74HC04 or similar – Must actively pull high to maintain noise immunity<br />
Single Supply Operation<br />
Notes:<br />
(1) Power supply decoupling capacitors C1 and C2 should be connected as close as possible to the pins of the<br />
gate driver and must be sized to have appropriate ESR and ripple current capability for the <strong>IGBT</strong> being driven.<br />
(2) C trip should be connected as close as possible to the pins of the gate driver to avoid noise pick-up.<br />
(3) All zener diodes 1W, all resistors 0.25W unless otherwise noted.<br />
