Part Number: DRV8873H-Q1EVM Hi all,
I have designed motor drive using DRV8873H-Q1 (HARDWARE VERSION)
1) selected mode=H for PWM
2) pl let me know what is the max PWM frequency ?
3) Can some one share out1 & out2 wave forms w.r.t. IN1 & IN2 in PWM mode…
Part Number: DRV8873H-Q1EVM I have scanned the datasheet of the DRV8873HPWPR DC motor driver and I haven't found anything on the maximum current that the DVDD (Internal regulator) can source. I want to know if It can be used to power an arduino (which…
Part Number: DRV8873H-Q1EVM Other Parts Discussed in Thread: DRV8245-Q1 , DRV8145-Q1 , DRV8873-Q1 , DRV8706-Q1 Hello,
I'm trying to use this part together with a pair of LC filter to drive my Peltier element.
I'm using the software in PWM mode, even though…
Part Number: DRV8873H-Q1EVM Hello,
I have 2 different PCB, but both have same connection (shematic enclosure).
Both working, but if I drive them same PWM I get different Voltage/Current in motor ?
What can be wrong. If there is (however???) something different…

Hi team,
Here're 2 questions from the customer may need your help:
1) It is noted that the choice of bulk capacitor also greatly affects the overall EMC and response performance. The selection of this capacitor is not detailed…
Ryan,
My question is the length of copper thickness DRV8243H-Q1EVM, as I asked the thickness of DRV8873H-Q1EVM in the 1st post.

Hi team,
Here's some questions form the customer may need your help:
In hardware mode:
1. What is the minimum PWM duty cycle for the pwm control of 19KHZ to work properly? (Consider…
Part Number: DRV8873H-Q1EVM Hello,
I want to operate a TEC element with controlled current. As a controlling device I use a Raspberry Pi which outputs a PWM Signal (f: 40kHz). With this signal I want to switch the circuit that goes to the TEC element…
Part Number: DRV8873H-Q1EVM Other Parts Discussed in Thread: DRV8873 Hi all,
sorry for my poor english...
I've made a board based on drv8873H. My problem is that the IC burn very frequently on a minimal overload.
VM is 24V, the load is a linear actuator…
Hi Prema,
The continuous current that can be supported by the device depends on the total power dissipation in the device, the PCB design and Ta the ambient temperature of operation. More information on how to calculate the drive current vs. power dissipation…
