Other Parts Discussed in Thread: TIDA-00757 Need your help to understand P-MOSFET Q1 connection in below circuit in TIDA-00757. Here VBATT is supply and 6V is generated out of VBATT, is that correct ?
In P-FET usually source is connected to the supply…
Part Number: TIDA-00757 Tool/software: Code Composer Studio I am designing a BLE lock on CC2640F128 (RHB) (I can't change this) so i was looking for an example in the firmware of this board, but I found that it was updated to CC2640R2 chip.
Can you…
"On TI reference it shows the buck input accept range from 3.7V to 6V. We design our system to work on voltage range from 4.4V to 6V."
Did you also modify the power portion too? In TIDA-00757, the selected TPS62745 accepts voltage from 3.3V to 10V. What…

I have experience with the SimpleLink CC13XX / CC26XX products, not the LP55231. How are you managing the EN and CLK lines (along with INT/TRIG if used)? You should post to the Power managment forum if you have specific questions regarding this device…
Hi Raghu,
Thanks for your interest in TI FETs. Your implementation looks OK. You can see similar example in the TIDA-00757 reference design. Please keep in mind that if your battery voltage drops below 2.5V, then we cannot guarantee rds(on) as VGS …
Ankur,
I believe you entered the wrong TI design number for the part number.
You have TIDA-0002. This is for the HEATEVM, and it does not reference any motor control.
The pdf you reference is for TIDA-00757
Please re-post your question with correct…
