Gate Driver ICs Forum Discussions
Hello,
I would like to use the IFX007T for driving a resistive load (~10Ohm).
I would like to drive it at 200Hz, how can I calculate the resistor at pin SR for rise-time and fall-time?
Thank you very much in advance.
Best Regards.

I am currently using the IRS21084S as a gate driver for a half-bridge inverter, but I am having trouble, so I would like to know about a driver that meets the specifications below.
DatasheetIR2108(4) (S) & PbF (infineon.com)
Compatible products with the same pin assignment as IRS21084S.
〇 HO and LO drive output current (current supply capacity) is large (preferably 1A or more if possible)
〇Compatible with IRS21084S
・SOIC surface mount 14 pin, same pin layout
・it Has HIN input and inverted LIN input
I alreadly asked this community the same question and have gained the following two ICs,

But these proposed ICs have different pinouts(2), so we are looking for another alternative IC if possible. I would appreciate your feedback.
Hi,
The RFE pin is used to enable, fault reporting and programmable fault clear timer, it should only get triggered by either ITRIP OCP event or under voltage protection. Somehow, this pin is triggered by other events in our design, we have checked ITRIP, VCC, VBS are all fine, no voltage protection as well. This RFE triggering therefore causes our motor to stop at high speed (~400RPM for ceiling fan), which is undesirable.
Can we disable this RFE pin? How can we disable?
If we are not using the pins, how large is the recommended resistor value? 2M?
Currently, we are connecting to 1M, but it seems not enough to disable it.
We also observed over heating of this gate driver IC. After a few rounds of RFE triggering, we stopped the system, and once we turned it on again, motor was not running. Later on, we realized that at stop state the gate driver reached~130deg C already.
Could you advise why is this happening and how can we prevent overheating?
Thank you.

Dear all
I am developing a smps full bridge input 48 Vdc, output 200+200Vdc 4800 W, 50 kHz.
I want to use the driver IR2110 and in the bridge there are two mosfets in parallel in each channel.
Can i use this drive to control these two components? If no, can you suggest me other options?
Sincerelly
Marcelo
Show LessIn the data sheet (Page 8), the target pins (HIN, LIN, ITRIP, EN) are listed in the Vin, clamp section.
In addition, the internal circuit diagram shows a clamp diode in the internal circuit of the HIN and LIN pins, which indicates that the pins are clamped at 5.2V. (Page13)
However, there is no clamp diode listed for the internal circuitry of the ITRIP and EN pins.
Which description is correct?
Do the ITRIP and EN pins have internal clamping diodes?
Data sheet

There are two problems with the current TLE7242 EMC:
1. One is caused by the 25M clock.
2. One is caused by 4K constant current drive valve body
How to improve or slove it, Thanks

Show LessPlease tell me if it is necessary to process the G-to-S resistance to determine the OFF of the external FET.
I checked on the data sheet, but there was no built-in resistor in the IC, and there was no description of an external resistor around the FET, so I could not confirm whether the FET would be turned off in the case where the 2ED2410 was indeterminate (for example, a failure or no power supply).
