Part Number: DRV8881 Tool/software: Hi All,
I have a question about the DRV8881.
I have a DAC connected to VREF to dynamically change the current limit value.
If I change the VREF voltage, how long does it take for the output to stabilize?
Also, if…
Part Number: DRV8881 Tool/software: Hello everyone,
I've checked the DRV8881 documentation regarding the integrated current limiter. Is it correct that a Ref.voltage of 1.625V with 200mR sense resistor should result in a 1.23A current limit, when TRQ0…
Part Number: DRV8881 Other Parts Discussed in Thread: DRV8434 Hi All,
I have a question about DRV8881.
The recommended operating range for VREF is listed as 0.3V to 3.3V. There is a note that says "Operational at VREF ≈ 0 to 0.3 V, but accuracy is degraded…
Part Number: DRV8881 Other Parts Discussed in Thread: DRV8426 , DRV8428 , DRV8434 , DRV8424 Hi team,
can DRV8881P be used in the slow decay mode? now the motor is under subdivision operation with 1.8 step angle and peak current be 2A. the max speed set to…
Part Number: DRV8881 Hi Team,
1.Is it possible to judge whether the DRV8881EPHRT is damaged by using conventional tools such as a multimeter?
2. Use a multimeter to measure the capacitance value between the pins of the chip, and find that the value is…
Part Number: DRV8881 Hi team,
This device, DRV8881PRHRT, is now used in my customer's nine-inch dome machine. But now the nine-inch dome machine is very hot, so there is a problem that needs your support:
1. Is there anything special about soldering…

Part Number: DRV8881 Hi All,
I have a question on DRV8881.
The maximum recommended operating range of VREF is V3P3, If the output of V3P3 is 2.9V, is it a rating violation if 3.6V is input to VREF?
Or is VREF capable of inputting up to 3.6V regardless…
Part Number: DRV8881 Other Parts Discussed in Thread: DRV8825 Hi team,
My customer is considering if DRV8825 can be used as DRV8881P P2P compatible assembly option.
Do you think it is possible?
My customer thinks the interface pins (#21-24) can be switched…
Part Number: DRV8881 Hi Team, we would like to seek on how to calculate for the output voltage on purely resistive load.
The supply voltage to the DRV8881P device is 14.7 to 15V. The torque is set to 99%. The AVREF and BVREF pins are shorted to V3P3.…
