Hi Cole,
Thanks. the concept of sqrt(3) is from Jiri of TI in E2E post at regarding the line power and input power. In TIDA-00281, he said, "
30 A is the maximum input DC current. Power per phase is Iin/sqrt(3) = 17.32 A
The motor drive is rated…
Part Number: TIDA-00951 Hi,
I have couple of questions on the boost mode,
What is the purpose of delay_1 and Tdelay_2 ?
there is need to be ZVS is the transistors on the low side?
A very large power losses are created on the transistors during the…
Part Number: LMT86-Q1 Other Parts Discussed in Thread: LMT86 , TIDA-00774 , TIDA-00901 , TIDA-00281 , Hello,
I am wondering how R and C were selected for the temperature sensor LMT86/87 output circuit in different TIDA?
1) TIDA-00774 specifies RC values as…
Part Number: TIDA-00951 Hi,
I flashed the firmware to the tida -00281 via jtag (btw there is a mistake in the design- pin 7 and pin 1 are flip at the jtag port!!).
Can you please explain me what the firmware are doing?
is it step down the voltage and…
Part Number: TIDA-00281 Hi,
We made TIDA-00281 board with some of the modifications as listed below.Our application is to run 60V/250W BLDC motor for EV.
(1)We made this board on two-layer PCB.
(2)No Flyback sections used as we have availability of all…
Hi Chandra,
"I did capture waveforms from DRV8353RS-EVM board and I do see same spikes even in EVM board." - That is normal.
"Does it mean my probes are inductive or EVM board is not designed well ? "- The main problem with oscilloscope probes…

Part Number: TIDA-00036 Other Parts Discussed in Thread: TIDA-00364 , TIDA-01485 , TIDA-00281 Tool/software: Code Composer Studio Hi All,
I am using inverter TIDA-00364 to use 1Kw BLDC motor. In TIDA-00364 datasheet they are mentioned for 48 - 52 volt to…
Hi Laura, we don't have a 1/2 bridge with these protection features; however, there is a reference design that provides a complete solution.
