Part Number: DRV8824-Q1 Other Parts Discussed in Thread: DRV8824 Hi all Would you mind if we ask DRV8824? <Question1> How much is the Tdeg time? There is no description on the datasheet. DRV8824 shows 3us typ. Is it the same? <Question2> How much is the…
Other Parts Discussed in Thread: DRV8824-Q1 Dear, Sir.
My customer is looking for Full-step Stepping motor driver.
The driving current is so small as 67mA.
DRV8824-Q1 has mode select which can set Full-step.
Is it no problem to set ISENA/B chopping…
Part Number: DRV8824-Q1 Dear sir,
below figure is our AVref voltage and Bout2 current signal
we think Bout2 current's high frequency is because of AVref voltage's
Is there any setting or solution to filter out the chopping frequency on Bout2?…
Other Parts Discussed in Thread: DRV8824-Q1 Hello,
Please answer following question from customer.
DRV8824-Q1 datasheet has no explanation about Over Voltage Protection of VM voltage.
Does DRV8824-Q1 have Over Voltage Protection?
In case…
Other Parts Discussed in Thread: DRV8824-Q1 Dear sir,
About DRV8824-Q1, Chapter 9.2.2.2 Current Regulation.
Below is our design sample:
For Equation(4):
VREF=3.3V
Rsense=0.4 ohm
=> Ifs = 3.3/(5*0.4) = 1.65 (A)
for Equation(5):
VM=12V…
Other Parts Discussed in Thread: DRV8824-Q1 , DRV8824 Hi Champs,
Customer would like to use DRV8824-Q1. but customer wants to make the stall function with MCU.
Could you please reference SCH or configuration?

Hi Ushikubo-san,
Toshio Ushikubo said: In Slow Decay Mode, if the current has not reached target value at the end of PWM cycle, will drive mode continue to next cycle and cause same behavior with Fast Decay Mode?
Yes, the DRV8824-Q1 will continue…
Other Parts Discussed in Thread: DRV8824-Q1 Dear all,
Is it possible to detect open load by DRV8824-Q1?
I have understood this device does not have FAULT to detect open load.
However my customer want to use this device and detect open load.…
