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,…
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: DRV8871-Q1 Hi,
I am working with this part to drive a motor with this characteristics
No Load Current = 150mA
Stall current 4A max
I set the H-bridge for max current limit of 3.5A so it never reaches lock current, and I am PWM @ 400Hz…
Part Number: DRV8871-Q1 Hi team,
Greetings. I have a question about the VM bulk cap of DRV8871-Q1.
The parameter is that VM=12V coming from automotive battery, normal working current=1A, stall current=2.5A.
Duty cycle is 100% only using high or…
Part Number: DRV8871-Q1 Dear, Sir.
My customer is looking for the alternative part instead of TA8050FG/Toshiba.
I am thinking DRV8871-Q1 would be suitable for that.
As the double-confirmation, I would like to make sure the Rds(on) definition.
…
Part Number: DRV8871-Q1 Hello Guys,
Our customer is driving a toroidal inductance of about 500uH (not a motor). As he understands it, in order to "change direction" there are inductive effects to related to changing the direction of the current need…
Part Number: DRV8871-Q1 Dear, Sir.
My customer is considering to apply DRV8871-Q1 for their system.
They don't have an experience for thermal pad soldering because the inspection
is impossible. So, they are asking about the thermal performace degradation…
Part Number: DRV8871-Q1 Hello,
Our customer is looking for a way to sense the current flowing through the motor. Can they have a sense resistor between Pin 7 (PGND pin) and Power ground?
Regards,
Roland
Part Number: DRV8871-Q1 Hi, team.
The data sheet has the following description, is 800 ns typo?
"The voltages applied to the inputs should have at least 800 ns of pulse width to ensure detection. Typical devices require at least 400 ns. If the PWM…
Part Number: DRV8871-Q1 Hi,
I failed to understand where exactly I do activate the PWM
If for example, I need to 75% PWM the motor CW direction how should the IN1 and IN2 driven and to what pin of the driver the PWM wave from the MCU should be connected…
