Hello to all!

I would like to know if the driver 1ED020I12-B2 can handle 3 IGBT Infineon FF200R12KT4 ( 3 IGBT for each channel ).

It will be used in a full bridge inverter, input 125 Vdc, output 220 Vac with isolated transformer.

Is just put separated gate resistor?

Sincerelly;

Hello,

Can half-bridge gate drivers like the IRS2007 and IRS2008 be controlled by DC voltages at the IN pin, or is there a minimum input frequency? The datasheet doesn't specify this. We are not using PWM, but rather just want to turn on either the high-side or the low-side driver for long periods of time.

Thanks,
Scott Show Less

Dear Infineon Team,

I wish to use this driver (2ED21084S06J) in my work to drive half-bridge inverter. I want to insert deadtime of up to 4.5 microseconds as this driver is capable to do the same.

I request Infineon driver team to send me PSpice model and symbol file for 2ED21084S06J.

Thanks and Regards,

Hello everyone, I use the gate driver ic IR2136, when I measure between VB1 and VS1 I haven't 15V, I have to put the source pin of the mosfet transistor at the GND to have a potential difference of 15V between VB1 and VS1.

i look at the page 5 of the datasheet of the IR2136 to help me

the values of the components : 1) 3x diodes 1N4007

2) 5x 1kohm resistors

3) 6x 1µF capacitors

4) mosfet STP43N60DM2

if someone has already worked on a circuit like this ? please give me some tips to correct this error.

Dear Team,

We are looking for solenoid driver IC's for both PWM & ON/OFF type solenoids with operating voltage of 6-60V and current output of 2.5A in Transmission control units kindly suggest us the suitable IC.

Also when we would like to know about the heat sink consideration for the DDPAK IC where datasheet suggest us to give PCB area of 76.2 x 114.3 x 1.5 mm copper area as a heat sink,

where as our PCB size itself is 100x150x1.6mm in which we need to accommodate 11 no's DDPAK IC'S how to provide copper area in such cases. kindly provide solution for this

Hi,

I made a motor drive using 6EDL04I06PT, STD16NF06T4 FETs (16A TO252), 0.033ohm triple shunt, 2.2uF bootstrap caps and 24ohm gate drives on all gates.

I laid out one PCB with this, and it works pretty near perfectly... but there was some switch ringing, and ringing on the shunt resistors which was causing occasional current trips, so when I respan the board (needed to change a few unrelated things) I moved the shunts around to reduce the loop areas and minimise the inductance.

The other change I made, was to use the NC pins to feed through the LO1,2,3 signals, which made for a much tidier routing with fewer ground plane breaks. Since the board is being used for low voltage (up to 48V) no concern about creepage distance.
Is this OK to do? The datasheet says n/c - not connected, which in my mind meant they were probably intended for this purpose, but now I'm less sure.
Despite being as close to identical schematically as conceivable apart from those layout changes, the board has destroyed two sets of FETs after only a few seconds of operation. Symptom has been that the low side FETs have had their gates burnt through - only tens of ohms between gate and source. High side FETs have possibly also died, but it's less clear cut; the gates still have high impedance and ~3Mohm drain source resistance.

Board has been run with 15V gate drive voltage, 24V supply.

Firmware being run on it is identical. I can still upload the firmware to the old version and have it spinning away happily.

Any advice? I have tried prising up the N/C legs on the gate drive, and it ran again, but breifly... I only changed the FETs that seemed to have died, perhaps they were all partially knackered.

I am designing a BLDC motor controller and facing some issues with using an IRS2007 along with IRFB3607.


For one phase, the high side and low side give clean wave forms as long as V_Pow is disconnected. Rise time - 300ns; Fall time-100 ns; On time - 312us; Period- 416us;

Once V_pow is connected, the input signal to the low side of the mosfet driver leaks to the high side and drives the gate of the high side mosfet. The gate of the low side mosfet is off.

This creates a high to high short over 2 phases of the motor and the motor immediately stops. This happened first time after running for about 1 min. Ever since, the motor does not run when powered by 3 phases.

The motor is a 48V 900W motor driven at 12V, no load (1A).

If driven by the two other phases, the motor runs.

------------------------End of current issue-----------------------------

Background:--------------------------

I have tried this configuration multiple times, at first I used a complimentary BJT (PNP_NPN) duo to increase the current pumped to the gate of the MOSFET



In this case the driver would work properly when V_POW was not connected but fail after V_POW was connected to 12 Volts.

Each time, with 3 phases and V_pow disconnected, the gate pulses would be in order. Once V_pow was connected, one phase would randomly fail before 1 cycle was completed.

After that the remaining 2 phases would happily power the motor till the failed Mosfet driver was replaced and then again within 1 cycle 1 phase would randomly fail.

In the above config, on mosfet driver failure, both HO and LO pins would be shorted with pins of V_Boost & V_in respectively. I presumed it was an internal MOSFET failure due to over current.

As of now I have destroyed 17 drivers trying to figure out what happened. Don't know what I am doing wrong, The power mosfets mosfets don't seem to fail. Max current through the power circuit is hardly 1 -2 amps.

Hello,

I have a circuit to convert 200 Volts to a regulated 160 Volts at 35 Amps, the cuircuit works ok.
I want to convert the circuit so it uses a N-MOSFET instead of a P-MOSFET and improve the switching efficiency and reduce the number of components.

What part do i choose?
