Other Parts Discussed in Thread: DRV11873 Hello,
As according to the user guide for the evaluation module, I removed the 0.0 ohm R5 resistor to allow the use of an external PWM. To test the functionality, I connected the PWM test pin from another board…
Other Parts Discussed in Thread: DRV11873 I need to control the motor orientation using a digital output (LOW or HIGH) from an external protoboard (e.g. Arduino or IOIO). For that, I need to remove the J1 jumper and connect the output pin from the protoboard…
Other Parts Discussed in Thread: DRV11873EVM , DRV11873 Hi there,
I'm try to control a motor using an Android device in conjunction with an IOIO board and the DRV11873EVM. I removed the R5 resistor so I can provide an external PWM signal. However, the motor…
Other Parts Discussed in Thread: DRV11873 Can I connect the FG open drain test point output to the Arduino Analog input pin? I don't think I can use an DigitalInput since it only reads HIGH or LOW and I need to obtain the frequency value to calculate the…
Other Parts Discussed in Thread: DRV11873EVM , DRV8313EVM , DRV8313 , DRV11873 , DRV8301 , DRV8302 Can I send an external PWM signal to the DRV11873EVM to set the motor speed, want to ensure that I can drive the motor controller properly before desigining …
Hi Chris,
DRV11873EVM works fine so can you try replacing your PWM circuit with the PWM signal generation circuit in the EVM? Clearly, it is your PWM circuit that is overloading the V5 power supply.
Regards,
Vishnu.

The use of DRV11873 to drive brushless motor encountered several problems looking for guidance from the team.
1. Control the motor with DRV11873EVM circuit diagram. PWM speed regulation…
Hi Sammi,
Thanks for posting your question in MD forum. Do we know what the maximum load current is during startup at high load? Maximum current that the device can support is 2A. Is the customer using DRV11873EVM or custom board? What is the value of…
Part Number: DRV11873 Other Parts Discussed in Thread: , DRV10987 , DRV10975 , DRV10975EVM , DRV10987EVM Dear Sirs,
We use your evaluation board DRV11873EVM to test the DRV11873 PWPR again, still found the same problem.
The motor start stop frequently at the…
Part Number: DRV10975EVM Other Parts Discussed in Thread: DRV11873EVM , I am evaluating TI motor drive ICs for a low power cooling fan application, we do not have the motors yet so I am experimenting with motors from consumer drones with the motors free…
