Timing Chart
1) Short Circuit Current Protection (protection with the external shunt resistor and RC filter)
a1. Normal operation: IGBT ON and outputs current IC.
a2. Short circuit current detection (SCP trigger)
It is recommended to set RC time constant of 1.0ตs so that IGBT shuts down within 2.0ตs when SCP is triggered.
a3. All low side IGBT
?s gates are shut down (soft turn off).
a4. All low side IGBTs turn off.
a5. FO outputs for tFO=45ตs (Min).
a6. LIN=L
a7. LIN=H, but all IGBTs keep OFF during SCP=H.
a8. FO finishes output , but IGBT
s don?t turn on until inputting the next ON signal(LIN=L?H)
IGBT of each phase can return to normal state by inputting ON signal to each phase.
a9. Normal operation: IGBT ON and outputs current IC.
Notice
SCP works only for low side IGBT only.
In case of SCP trip and FO output, please stop controlling IPM quickly to avoid the abnormal state.
