SHORT CIRCUIT PROTECTION
Operation of Protection Circuit
1. In the case where the gate voltage is "H" and the collector voltage is
high, the hybrid IC will recognize a short-circuit condition and
immediately reduce the gate voltage. Additionally, it will output an
error signal ("L") which indicates that the protection circuit is
operating at the same time from Pin 8.
2. The protection circuit resets if the input signal is "OFF" when the
premised 1~2msec passed. ("OFF" period needs 10μm or more.)
3. When the output rises, the controlled time detect short-circuit
(typically 2.6μs) is set up so that the on-time of the IGBT can be
secured properly. It is possible to adjust this time by connecting a
capacitor (C
trip
) between Pin 2 and Pin 4.
Adjustment of Output Fall Time
When the protection circuit is operating, the speed of reverse bias can be
adjusted by connecting a capacitor (Cs) between Pin 6 and Pin 7.
