Part Number: DRV8844 Hello,
I've designed a custom board with the DRV8844. This is the first time i'm using this IC and I need help in reviewing and cross checking the schematic. I can send the schematic image as a private message. Please help me regarding…
Part Number: DRV8844 Hi Team,
Can you please suggest few design inputs to plan for redundancy for DRV8844 motor driver, used to drive DC motors in a rover kit?
Our customer is connecting two battery operated motor to one DRV8844 motor driver, all together…
Part Number: DRV8844 Other Parts Discussed in Thread: DRV8873 Hi Experts,
Seeking your assistance on this query from Cx:
Can you please let me know whether DRV8844PWP can drive battery operated DC motor?
If yes, can we connect 6 motors to one driver with…
Part Number: DRV8844 Hi team,
My customer is using DRV8844 and facing a nFault triggered when VM powering up.
As shown below, Yellow: nFault Pin voltage, Green: VM voltage
And if we increase the VM rise speed, like 2ms, no nFault is triggered. But the…
Part Number: DRV8844 In a previous thread TI_Guru mentioned that Vcp should be 11V above VM. If my input voltage is 24V, doesn't that mean the voltage rating should be at least 35V? Probably more like 50 or 100V? Why does TI suggest a 16V rated capacitor…
Part Number: DRV8844 Hi,
In page 3 and page 11 of the datasheet, it says that a 0.01ufF100V Capacitor is required between CP1 and CP2. On page 8, in the block diagram, the charge capacitor between CP1 and CP2 is 0.1uF. Which is the correct value for that…
Part Number: DRV8844 Hi TI expert,
How can we test DRV8844 for Massive Production Test?
Do we have methods like certain electrical load to simulate the stepper motor to test DRV8844?
B R,

Part Number: DRV8844 Other Parts Discussed in Thread: DRV8251A
Hello,
I am designing a control board for bistable water valves operated at ~9V. I'd like to control the on/off solenoid current bursts (300mA for 250ms resp. -50mA for 60ms) and to detect…
Part Number: DRV8844 Hi Team
When customer evaluating DRV8844, they asks whether continuous motor drive output current can reach 3A, if with good heatsink natural cooling? since on datasheet the max is 2.5A, but don't know the thermal condition
