Part Number: DRV8874 Tool/software: In order to control the forward or reverse direction of motor(mb3657-2465e, 24V), I applied DRV8874 and designed it as shown in the figure below.
I only designed it based on the datasheet. Please review if there is…
Part Number: DRV8874 Tool/software: Dear Experts, please give me some comments on BIAS voltage. In order to reduce the power consumption, I will turn off the VM pin voltage of DRV8874 when system in stand by mode. At this time, the BIAS voltage on VREF…
Part Number: DRV8874-Q1 Tool/software: Dear team.
Do we have Pin FMEA report of DRV8874-Q1? They found short between pin11 and pin12, and need to know the failure mode of this.
Best regards, Yuto
Part Number: DRV8874 Other Parts Discussed in Thread: DRV8235 Tool/software: I'm trying to use DRV8874 to control a 24V 5A DC motor.
However, it does not include sensorless speed control.
DRV8235 seems to be capable of sensorless speed control, but…
Part Number: DRV8874 Tool/software: 1. When set Pmode = high,IN1=HIGH, IN2= PWM, so it works between forward and brake.
2. When set Pmode = low,PH =HIGH, EN = PWM, so it also works between forward and brake.
The 1&2 forward PWM duty is same. But the…

Tool/software:
Hello, We have found that the trise, tfall, tpd, and tdead times for the DRV8874PWPR are significantly off from their typical values. In the case of tpd, there is more than a factor of 2 between the typical time…
Part Number: DRV8874 Other Parts Discussed in Thread: STRIKE , DRV8873 , DRV8244-Q1 , DRV8243-Q1 , DRV8245-Q1 Tool/software: I read the detailed design procedure in datasheet as reference for my design. The example uses 35C/W as RθJA, but does not indicate…
Part Number: DRV8874 Tool/software: Dear Support Team,
I have configured DVR8874 to be in over-current only fault mode:
But in the application I see charging of a external elko to look like this:
I would expect to not have "current…
Part Number: DRV8874 Hi Team,
Using the current sampling inside the chip is not accurate. For example, when using en/ph mode, the actual current of the motor during movement is 60mA, while the current of the iPropi pin of the reading chip is 120mA.…
Part Number: DRV8874-Q1 Other Parts Discussed in Thread: DRV8874 , DRV8243-Q1 , , DRV8873-Q1 I'm having a problem using the DRV8874 with a 775 DC Brushed motor, which recommends a startup current of 10A.
Setup: PMODE grounded (PH/EN mode), IMODE Grounded…
