Part Number: DRV8871 Other Parts Discussed in Thread: DRV8870 , hi team:
my customer use DRV8871 and DRV8870 to evaluate the BDC ,but check with the DRV8871EVM board, we found this issue:
1.The normal starting current waveform is as shown in the figure…
Part Number: DRV8871-Q1 Dear team,
My customer wants to use our device to drive a coil, and there will be bidirectional current on this coil. In addition, this coil has a special feature, when the current flowing through the coil is less than 0.1A, its…
Part Number: DRV8871 Other Parts Discussed in Thread: DRV8870 , DRV8872 Hi,
Because of the supply problem, I consider replacing DRV8871 with DRV8870 in mass production. Discarding the IChip feature is acceptable. I wonder if it's theoretically feasible…
Part Number: DRV8871 Hi there,
I currently designed a motor controller with the MC33926 controller for a dc brushed motor. after implementing this controller we noticed current spikes from the initial movements for the motor (as expected) and then implemented…
Part Number: DRV8871 Hey team,
Just wondering if we had a recommended wattage for the resistor on ILim? Trying to figure out if a customer should use a 402 or 201 sized resistor.
Thanks,
Cam
Part Number: DRV8871-Q1 Other Parts Discussed in Thread: DRV8871 , DRV8872 I have developed a board that is intended to drive different types of motors. One application is a "smart" servo motor which has an integrated controller and an RC (PWM) interface…
Part Number: DRV8872 Other Parts Discussed in Thread: DRV8871 , DRV8873 hi,
customer used to use DRV8871, now they want to P2P change to DRV8872? is there any concern or points for that?
I checked the pin definition and find the pin4 and pin7 is different…
Part Number: DRV8871 My customer is using DRV8871DDAR.but they want to use DRV8871DDARQ1(Automotive version)temporarily.
In the datasheet, there are some spec difference.
Is it OK to replace from DRV8871DDAR to DRV8871DDARQ1 directly ?
Is the spec differ…
Part Number: DRV8871 Other Parts Discussed in Thread: DRV8870 , DRV8872 Hi,
Customer want to know, can they take logs of current consumption by motor on MCU using current regulation (ILIM) or current sense pin (ISEN) of motor drivers like DRV8871,72,70…
