Part Number: DRV8874-Q1 No.1
Is the VM line affected by motor surge from the motor connected to the OUT1 and OUT2 terminals? If so please tell me what to do.
No.2(Related to question No.1)
Could you tell me the CBulk capacitance value of the VM line in…
Hello Yukio,
Yes, you can connect 5V directly to pmode
Yes, you can absolutely use those capacitors. The capacitors listed in the datasheet are the recommended values.
Thank you,
Audrey

Part Number: DRV8874-Q1 Hi, Technical resposible!
the technical specification of our application can be classified with this consumption range (IOUT < 0.4 A and 5.5 V ≤ VVM ≤ 37 V).
Could you confirm how I calculate the Analog current output…
Part Number: DRV8874 The DRV8874 datasheet states: "The internal blanking time helps to prevent voltage and current transients during output switching from effecting the current regulation. These transients may be caused by a capacitor inside the motor…
Part Number: DRV8874-Q1 Hi team,
Is there any problem to contorl PWM signal (IN1/IN2) before waiting tWAKE1 or on transition from sleep mode to active mode? We use "PWM mode".
We understand that changing this device to active mode from sleep…
Part Number: DRV8874-Q1 Hi, HW guys in this forum,
I downloaded DRV8874-Q model for simulation from: https://www.ti.com/product/DRV8874-Q1?keyMatch=DRV8874-Q1&tisearch=search-everything&usecase=GPN
I have only LT-SPICE installed on my PC, so i…
Pablo Armet said: The diagram in the datasheet does not show the extra time required for the driver to go into decay mode.
Then the diagram is wrong, isn't it?
Part Number: DRV8874 Other Parts Discussed in Thread: DRV8873 , Need to construct a bus converter that takes Vin = 15V and outputs 60V or 75V depending on the turns ratio of the transformer.
Would operate the DRV8874 in EN/PH mode, driving PH with 50%…
Part Number: DRV8874-Q1 Hi Experts,
When DRV8874-Q1 is working as direct drive forward-rotating. High side OUT1 short to GND. The nFAULT was driven LOW. What can trigger nFAULT LOW?
According to the fault condition,
The current mirror is on low side…
