Part Number: DRV8843 Hi,
I'm using the driver for Dual Brushed DC, the PWM that i generating is 2.5KHz and the controller is Spartan 6 (Xilinx's FPGA).
It seems that once in a while the Bridge A stuck ( the motor doesn't move although the right…
Part Number: DRV8843 Other Parts Discussed in Thread: DRV8841 Hello,
I was looking at DRV8843 datasheet ( http://www.ti.com/lit/ds/symlink/drv8843.pdf ) and I had some confusion. Two diagrams in the datasheet do not match and I was wondering if I am…
Part Number: DRV8843 Is fPWM an externally applied signal? Or is it internally generated?
The datasheet implies externally applied in table 6.3 recommended operating conditions, but in table 6.5 electrical characteristics, fPWM is referred to as internal…
Hi Caitlyn,
It is possible to drive a stepper with the EVM, but not the GUI.
Either the code in the mcu would have to be modified, or an external mcu can be used to control the DRV8843.
Other Parts Discussed in Thread: DRV8843 I have a customer that is using the DRV8843 in a stepper motor drive applicaiton. They have noticed a strange phenomenon and would like to understand if they are doing something wrong. I will try to describe the…
Other Parts Discussed in Thread: DRV8843 , DRV8841 Hi
My customer is considering the motor driver, they're the candidate of ON-Semi LV8702V. LV8702V: http://www.onsemi.jp/pub_link/Collateral/ENA2121-D.PDF
They need Full Torque at Half Step driving…
Other Parts Discussed in Thread: DRV8843 Hello,
I am using the DRV8843 for controlling two DC motors simultaniously. The motors consume 0.1mA with no charge, each one.
When testing the driver just with a simple PWM, the motors consumptions are OK…
Other Parts Discussed in Thread: DRV8843 Hi I am currently trying to use the DRV8843 to drive two DC motors that can consume up to about .5 A when fully loaded. I am essentially using the same logic as the diagram on page 2 of the datasheet, and I have…
Other Parts Discussed in Thread: DRV8843 Hello,
I'd like to know if there is a sort of trick for dealing with the driver DRV8843. I'm trying to use it with two DC Faulhaber Motors, but it never works entirely, just one channel works. I'm not using current…
Other Parts Discussed in Thread: DRV8843 I need to know what is the internal LDO maximum output current during switching with 16KHz & 32KHz.
this is not mentioned in the datasheet
It seems that beside the Vm*Ivm, Rds(on) and drive current factors…
