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-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…
Hi Jeremy,
I'm glad you were able to find the root cause.
Jeremy Novoa said: If the H-bridge is set to regulate at 3.05A (Itrip), what happens if the inrush goes over 3.7A? Does it regulates or goes into over current? I am under the assumption that…
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 to…
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.
The datasheet…
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?

Roland
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 Other Parts Discussed in Thread: DRV8870 , DRV8873 , DRV8243-Q1 Hi Team,
Q1:
The input terminals IN1 and IN2 of DRV8871 input static data. For example, IN1=1 (high level), IN2=0 (low level), the duration is 200ms, then IN1=0, IN2=0,…
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 low voltage…
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…
