Regarding the datasheet Fig.36, the breakdown voltage drops when junction temperature is low.
Could you please tell me the reason?
If we do not program the address from 0x4001 to 0x402E,
does it will effect the IC movement?
I am developing a solenoid controller board using the TLE92464ED and am having problems getting the chip to stay in mission mode. I have configured the chip as follows:
- Disabled Clock WD, SPI WD, supply tests. Enable 3.3V IO and CRC checking in GLOBAL_CONFIG.
- Cleared any errors present from reset in GLOBAL_DIAG0/1/2 reg.
- Configured the channel with solenoid attached to use ICC in MODE register and changed the slew rate to 1v/uS in the CH_Config register.
After setting up as described above I check the FB_STAT register and see only OLSG_WARNx_CHK_NOK warnings on all channels which I believe is expected since the channel has not been enabled yet. Next I set the chip to be in mission mode and then enable ch0 (solenoid attached). The chip successfully transitions to mission mode and shows the channel is enabled and will stay in this configuration enabled in mission mode. If I now change the value in the SETPOINT register to a non-zero value I can see a short voltage pulse and then the chip immediately goes back into setup mode and ch0 is disabled.
Am I missing something in the configuration that is causing this behavior? I hope someone will be able to point me in the right direction.
I have checked the hardware side and can measure the resistance of the coil across the input leads.
Hi, Can any suggest the Most Popular Analog CCM PFC IC from Infineon. I have external Aux supply to start IC. Power Range - 1KW to 2.4KW. My LLC is IC is having Brownout Protection and PFC Disable Function @ Light load. So for PFC no need of Brownout Protection but PFC disable at light load is preferable.
Hi Team ,
We wanted Design with IR38164 below requirement
Input 12V and Output - 5V : 15A Typical and Peak current 25A , Data sheet Mentions Output can be set through resistor Divider on Feedback pin or PMBUS.
Could please provide more details on Setting VOUT =5V on Resistor Divider and also on compensation values.
Both the TDA38740/25 and TDA38640 datasheets reference an App note about PMBus - AN_2203_PL12_2204_184108:
I was able to find an AN2203 - https://www.infineon.com/dgdl/Infineon-AN2203_001-32909_0C_V-ApplicationNotes-v04_00-EN.pdf?fileId=8ac78c8c7cdc391c017d0d439ad269d0 – but it is an obsolete Cypress application note.
Can you please point me in the direction of AN2203 that discusses PMBus? Thank you.Show Less
We are in the development phase of a project using the PXM1310 and PXE1110 controller ICs. Up until now we have been using PowerCode to configure the parts but once we are in production we would like to load the configuration automatically via I2C during board testing at the same time that we load the other programmable parts on the board. we would like to do this without having to use the PowerCode graphical interface, which requires user intervention. However, the standard datasheets on the product page do not contain any information on part programing or internal registers. Where can I find information on the internal registers etc that would allow me to program the internal NVM of these parts? Alternatively, does PowerCode have a command line interface that we could use to automate programming?
Note that our production volumes are too small and production lead time too tight for us to order pre-configured parts directly from Infineon.Show Less
For designs requiring more than 40A, can we combine multiple POLs to support higher loads? For example, if we want to provide 100A, can we combine three TDA38640, TDA38641, or TDA38740 to source 100A? Do these modules support some form of current sharing or communication between them to implement phase control? My customer does not want to use a controller and power stages. They want to minimize their component count and board space, and are looking at Point of Loads with SMBUS (I2C) based communication that support loads up to 100A.
Thank you, ChrisShow Less
the customer is using the design on the above coolset IC, and has shared problem faced by him:
Output---3 phase AC
Output Power:- 5 & 7.5Hp rating motor
Switching 20~ 100KHz
We have 4 Outputs on the secondary side.
- 5V / 1A - regulated (optocoupler feedback is from this voltage output)
- 7.5V / 0.3A Isolated and unregulated
- 17.5V / 0.75A Isolated and unregulated
- 24V / 0.6A Isolated and unregulated
When we try to increase the load on the secondary the PWM Controller goes into reset mode as the Bias voltage exceeds 22V.
After this, instead of using diodes for rectification on the secondary on 17.5V and 24V we used synchronous rectification on their respective low sides. After this the performance was much better and the bias voltage reduced to 17.5-18V
Can you please guide us on how to resolve the issue and get the same performance without synchronous rectification."---------------------Show Less
