Part Number: DRV8841 Other Parts Discussed in Thread: DRV8844 Tool/software: Hi,
Good day.
Pertaining to PN#DRV8841PWPR, may I know of this part support current adjustion or not?
If yes, how to adjust the current? Could you please reveiw and advise…
Part Number: DRV8841 I have a few questions about the DRV8841 and hoping you can help or point me in the right direction. I've implemented the DRV8841 in my design but with current regulation disabled, meaning the current sense inputs and current scaling…
Part Number: DRV8841 Hi Team,
Regarding Overcurrent Protection (OCP), what is the current value that is triggered by the overcurrent protection?
Regarding Thermal Shutdown (TSD), at what temperature will it be triggered?
And for Undervoltage Lockout…
Part Number: DRV8841 Overcurrent Protection (OCP)
Thermal Shutdown (TSD)
Undervoltage Lockout (UVLO)
The specifications do not provide accurate values
How much current will trigger overcurrent protection？
How much higher will the temperature…
Part Number: DRV8841 Customer purchased DRV8841 on ti.com and it looks like it has no OCP function: 1. The current probe reads the current at the OUT terminal; 2. VM=24V, RsensA=RsensB=gnd, Vref=3.3V, AIN1=3.3V, AIN2==BIN1=BIN2=AI1=AI2=BI1=BI2=gnd, AOUT1…
Part Number: DRV8841 Hi Experts,
Good day. Seeking your assistance on this query:
I would like to use the DRV8841 to drive a stepper motor. The issue is that this motor has a particular wiring and two phases, like shown in one of the attached pictures…
Part Number: DRV8841 Hi Team,
Pin15 of this chip is V3P3OUT output 3.3V/1ma, customer would like to know could it be used for pin12.13REF reference pin and pull-up resistor connected to reset pin at the same time? REF shows that the current consumption…
Hi Vasco,
Some motors have capacitors inside the housing. An internal capacitor would account for the transient you are seeing. Is this the case?
Can you provide a scope capture of the current transient and nFAULT asserting zoomed in?
If there…
