Hi,
Does 1ED3122MC12H have output short to ground protection (output short circuit protection)?
Solved! Go to Solution.

Hi,
It doesn't directly comes with OUT to Ground fault protection feature.
It comes with UVLO (Under Voltage Lock Out) protection feature, which can not protect against OUT to Ground short circuit faults for IGBTs.
In this case, If the VVCC2 (Power supply voltage of the output chip) goes down below VUVLOL2 -(Threshold voltage output side (OFF)) , the IGBT is turned off and the signals from the input chip are ignored until VVCC2 again reaches the power-up voltage VUVLOH2- (UVLO threshold output side (ON)) again.
Since, the mentioned voltage range for UVLO is only the positive voltages for 1ED31xxMC12H, the complete UVLO protection scheme is valid for MOSFETs but not the IGBTs.

Hi,
Are you referring to Short circuit protection for the OUT to Ground pins or the IGBT short circuit protection?

Hi Shivam,
Short circuit protection for OUT to Ground.
