Grady,
See my response below.
Grady Lee said: Q1) If you look at the Electrical Characteristics of the datasheet, the current for driving is FG pin sink current: Min 5mA.
If you use it with a current lower than Min 5mA, what problems are expected? (Please…
Part Number: DRV11873 Other Parts Discussed in Thread: MCF8315A , MCT8316A Hi Team,
Motor control:
Open-loop control: PWM signals with different duty cycles are directly output through the FPGA.
Closed loop control: Sets different speed and controls the…
Can you tell me the relationship between duty cycle and rotational speed at different temperatures of DRV11873? In the test, I found that under continuous temperature changes and the same duty cycle, the speed would jump

Part Number: DRV11873 Other Parts Discussed in Thread: DRV10983 , Dear Sir/Ms.
We have customers who use DRV10983 to design fans, and the terminal has defective products. It was found that PIN12 (5V) and PIN16 (PWMIN) were burned. The customer asked the…
Part Number: DRV11873 Other Parts Discussed in Thread: DRV10974 Hello,
My customer has been using LB11685AV(ON Semi), but it will be EOLed, so they have to find an alternative motor driver soon. If I checked cross reference, it gave me DRV11873. However…
