Hello,
Please check the state of the SRn pin. The note in 7.3.3 Decay Mode details that if the SRn pin is high the current is always in fast decay mode which is what we appear to see in the scope picture. This issue is unrelated to the current trip settings…
Part Number: DRV8885 Hello team,
My customer tries to calculate switching loss on DRV8885 with referring to app note, slva504.
To calculate switching losses we need fsw information according to the app note.
Could you let me know fsw value for DRV8885…
Part Number: DRV8885 Hi, Customer is developing a software reset for the application. In the background, I received the following questions. How many seconds does it take to go into sleep mode after setting the "nSLEEP pin" to Low? Customers want…
Part Number: DRV8885 Hello,
When the motor driver was set to 1/8 with indexer, it was written that AOUT CURRENT was 71% of full-scale and BOUT CURRENT was 71% of full-scale by default. Does it mean that if the user uses the TRQ pin, it can be further…
Part Number: DRV8885 Is a capacitor required for the RREF pin? ①EVM has a capacitor (2) No capacitor on the data sheet ③PFU now has capacitors Do you recommend the motor driver side when mounting? Which of the attached excel is better to implement? PFU_question…
Part Number: DRV8885 Hi Team,
My customer is using DRV8885, for the current regulation, what it means "Full step (2-phase excitation) with 71% current" in the datasheet (page 28)?
Does it mean that, for example, you set 1A threshold and actually…

Hi App
DRV8885 and DRV8886 are pin compatible?
Does it move as usual just by replacing DRV8885 to DRV8886 on the board?
Thanks
Yuki
Part Number: DRV8885 About setting of M0 and M1,
Are there any restrictions when switching settings during operation?
For example, Non-Circular 1/2→1/2 step→Non-Circular 1/2

Part Number: DRV8885 Hi Expert,
Customer is considering the reason of stall situation.
They found the current drop when the another phase is switched negative current to positive current with stall situation.
Could you please let me know the reason of…
