Hello TI team,
a) I am using lab 1b and motor is not getting start any special attention need other than labs user guide ? because if I run motor with normal V/f PWM pattern motor is getting start.
b) One more question…
Hello Niklas,
thanks for your feedback. First I will answer your question:
- Is the device set to DEM or FPWM mode? -> FPWM (MODE via 10k pulled to VCC) - The LM5122 HO signal is measured with reference to GND, so it mostly shows the SW, correct? -…
Hi Jason
The information used and referenced is as follows:
1. Lab 1b A. Project path C:\ti\motorware\motorware_1_01_00_18\sw\solutions\insstapin_foc\boards\boostxldrv8301_revB\f28x\f2806xF\projects\ccs
B. Using Instaspin_foc
C. The Gate driver uses DRV8353RH…
Hi Bob,
We add the 1Kohm push up to 1A and 1Kohm push down 1B and the problem is solved, so many thanks for your and Clemens' support;
Now we have a suspicion that the voltage state as below screenshot , so the output voltage is indefinited;
We will update…
Grounding the speed pin will only if DEV_MODE is set to 1b so that the device can go into sleep mode. In sleep mode, AVDD and the I2C bus are disabled so I do not think this is the cause since when applying 12V to VM you were able to measure AVDD as going…
for 1: Vbb is needed even if for AC coupled, so R49 is still needed , ( looks I replied wrong last time.)
for 2: you can DNI R13/R14, R21, R22, R23, R24, R25, R26, R27 and R28.
Also remove external bias.
There are two 50ohm inside 1A/1B and biased by…
Hi Jarrod,
That's a good point. I checked in design. In VCA die, SDOUT buffer is working on 3.3V supply. So when SDOUT is driven by VCA die, it will be 3.3V and when driven by ADC die, it will 1.8V. But since the SDOUT of two dies are shorted and the…
Thanks for the update. I ended up finding the instructions above and successfully loaded my configuration from the OTP generator.
I have a seperate issue (can open another forum post if necessary) where I cannot put the PMIC into "Test Mode" / Programming…
Part Number: BQ25700A Tool/software: In the datasheet, ChargeOption1 AUTO_WAKEUP_EN bit shows that a binary value of "1b: Enable <default at POR>, however, we're finding that the default is actually "0b", or, disabled. We can prove this by setting the…
