Fig. 10 RECOMMENDED I/O INTERFACE CIRCUIT
Fig. 9 START-UP SEQUENCE
Normally at start-up, Fo and CL output signals will be pulled-up
High to Supply voltage (OFF level); however, FO1 output may fall to
Low (ON) level at the instant of the first ON input pulse to an N-Side
IGBT. This can happen particularly when the boot-strap capacitor is
of large size. FO1 resetting sequence (together with the boot-strap
charging sequence) is explained in the following graph
a) Boot-strap charging scheme :
Apply a train of short ON pulses at all N-IGBT input pins for ad-
equate charging (pulse width = approx. 20
s number of pulses =10
~ 500 depending on the boot-strap capacitor size)
b) FO1 resetting sequence:
Apply ON signals to the following input pins : Br
→ Un/Vn/Wn →
Up/Vp/Wp in that order.
