Part Number: DRV8876-Q1 Other Parts Discussed in Thread: DRV8801-Q1 , DRV8874-Q1 , DRV8874 , Hi team
How should we control BMD motor driver as BLDC with external hall sensor?
Is DRV8776-Q1 or DRV8874-Q1 possible to use as BLDC motor driver instead of DRV8801…
Hello,
Again, there is no regulation available in the device at these current levels. See table below:
So there is no error amplifier. The output PWM will match the input PWM. A DCDC is closed loop and trying to regulate to a particular voltage.
Unfortunately…
In the mean, I made also measurements with 350uH,and I tested different samples.
The 350uH measurements (dI/dT = 40mA/us at 12V) confirm the "constant delay" assumption: With Vref=3.3V, the bridge trips 4.6us after IPROPI rises above 3.3V.

Part Number: DRV8873 Other Parts Discussed in Thread: DRV8874 , DRV8874-Q1 , INA181 , Hi Team,
My customer is bringing up the DRV8873 chip and has a few questions about the current sense.
1) For current sense Rs resistor, we have 1.1kOhm. So this cancels…
Alexander,
It really depends on the current requirements for the solenoid. We have integrated devices like the DRV8873-Q1 or DRV8874-Q1 that can drive 10A and 6A peak currents, respectively.
For more current, I would suggest a gate driver device like…

Hi Team,
The customer requested a motor driver to use as the spec below.
We recommended DRV8873-Q1 & DRV8874-Q1.

Jo,
Thank you for your help supporting our products.
For #1, we offer more details on our automotive grade version of the DRV8874, DRV8874-Q1. If the customer needs those type of details, they need to consider the automotive grade device:

Murali,
Yes. You can put an external current sense resistor at DRV8426E AOUT2 pin.
Also, would you check if DRV8874 or DRV8876-Q1 is available or not?
BTW, DRV8428E has 16 pin package. If the output current is small, you can check DRV8428E.

Maynard,
We do not recommend paralleling the channels. If you need more current and a similar device, please consider this option:
