Motor Control ICs Forum Discussions

Hi,

Hello

            This is the case when the trunk is manually closed while the electronic control module (ECU) of the power lift gate is no power supply with battery, all MOSFETs are off, and TLE92104 is also no power, then， pushed the trunk , It is a motor can operate as a generator. The generated current charges the DC-link capacitor. If VS rises too high over the MOS VDS (max)40V，The MOSFETs may be damaged，So，The Tle92104 also turn into the  overvoltage brake mode ，in this application ？When VS > VSOV PASS OFF, LS1 turns on to turn on the low-side MOSFET. if not， how to solved this problem ？ 

        Looking forward you feed back ！thanks a lot ！

We have the TLE9563-3QX on a PCB that we made (Not Dev Kit) but we are 100% of the connection. 
When we run the PMSM motor in OpenLoop : The Chip takes the 6 PWMs from the Microcontroller and open the Gates correctly.

But when we do the same procedure for Closed Loop:  The Chip takes the 6 PWMs from the Microcontroller but have no output on the Gates. 
When we checked the Failure Flags, we had no flag for this issue. 

Hi 
Thank you for infineon service.

How to set PFC for USA?
USA normally power is 115Vac.

But i can't set low voltage for USA.

So let me know how to set that and
How do you usually use 115v power?

Should I use a voltage dubler circuit?

I want to know solution.
Thank you.

ps. Could i get "EVAL-M3-IM564" Altium data(sch, pcb)?

[Question]

Does the device have Nominal Load Current?

[My consideration]

Although the Data Sheet of BTN9970LV has the figure of Overcurent detection (min=60A), this doesn't have the figure of Nominal Load Current.

I think that the amount of current that can flow in this device depends on  junction temperature of the package.

If the power consumption obtained from the voltage and current values is multiplied by the thermal resistance and added to the ambient temperature, and the junction temperature is not exceeded, I am aware that there is no problem.

This solution uses the Infineon motion control chip IMM101T to drive the motor. Through precise control algorithms, the motor can reach a high speed of more than 100,000 revolutions, which has the advantages of high efficiency and low noise. The chip has a built-in controller, driver and power device, which is highly integrated and simplifies external devices to the greatest extent, which not only enhances the anti-interference ability of the system but also reduces the cost.

The IMM101T chip already contains the MCE motor control algorithm firmware. By setting the parameters of the motor and hardware, the motor can run quickly and smoothly, which greatly shortens the development cycle.

Infineon IMM101T high-speed variable frequency hair dryer solution -- block diagram.

Main parameters and features:

· Control method: non-inductive FOC

· Current sampling: single resistor

· Working voltage: 220V AC

· Output power: 120W

· Modulation frequency: 20KHz

· Motor speed: 120000RPM @ 1 pair of poles

Hi,everyone

I want to use CYT2B7 and TLE9562-3QX to communicate via SPI, but I am running into some problems:

1.TLE9562 How should the power be supplied? What is the supply voltage? What happened after the successful power supply.

2. How do I connect two chips? Are there any other Settings required besides CS/CLK/MISO/MOSI of SPI?

3. Do I need any initialization Settings before I officially start SPI communication.

Thank you.
