Part Number: DRV8701 Other Parts Discussed in Thread: DRV8251 , DRV8870 , DRV8770
Hello
I am looking for a DC‑motor driver similar to the DRV8701 but with a much higher source/sink capability. The DRV8701 can only handle about 150 mA, and I need…
Part Number: DRV8701 Hello,
I have some questions about operating DRV8701 and H-Bridge on separate supplies.
In my application VM should be 24V and VBAT can vary between 0 – 28V. I always have 100% Duty Cycle.
In table 9 the minimum voltage…
Part Number: DRV8701 Hi Experts,
Would you kindly help with the customer inquiry below?
I have designed a BDC motor driver board that uses DRV8701 with Nexperia PSMN4R2-40VSHX FETs. Small numbers of these boards have been deployed to field and have…
Part Number: DRV8701 Tool/software: Hello
I'm using DRV8701 and i want to read the motor current using ADC on my MCU. /
Currently we drive the motor using fast decay (motor coasting). The datasheet specifies that SO is not valid during brake mode…
Part Number: DRV8701 Hi everyone,
Is it possible to dynamically adjust the current regulation (VREF) on the DRV8701 during operation control torque without using a microcontroller?
If so, what is the simplest way to implement this in hardware (e.g…
Part Number: DRV8701 Hi all,
We are considering the introduction of DRV8701. Is it possible to get information on the following? 1) I want to change the gate current. How can I set it? 2) If the capacity is not enough, can I use a buffer circuit?

Part Number: DRV8701 Hi,
I am driving a BDC motor using the DRV8701. The nFAULT signal is asserted, and I am trying to find the cause. I would like to send the circuit diagram and waveforms via private message. Could someone please provide assistance…
Part Number: DRV8701 Dear TI Engineer,
We encountered the following two issues when using DRV8701 to drive a DC brushed motor:
1) SO pin waveform issue
The pin definition in the datasheet requires no more than 1 nF of capacitance on this pin.…
