Part Number: DRV8251 Tool/software: Hello,
we are working on a design with DRV8251 to drive piezo loads with parallel 1 k resistance. A prototype (1 k load only, no piezo) showed nice operation at Vs 10 V and Vs 30 V. However, with 45 V Vs the DRV8251…
Part Number: DRV8251 Other Parts Discussed in Thread: DRV8874 , DRV8870 Our product currently have the A4950 driver and I want to use DRV8251 in HSOP package to upgrade the product with higher output current. My concern is the potential output signals jitter…
Part Number: DRV8251 Hi team,
Do we have an automotive version of DRV8251? I did not see it in TI.COM.
Can I promote DRV8243/4/5-Q1 to my customer as a replacement?
Regards,
Peter
Part Number: DRV8251 Hello MD,
Our Nextgen MX will use this pump: Boxer 5211.901 . This has a small 12V brushed DC motor (4W max.). However, there are cases where we drive it at only 2V (to lower the flow rate). Currently, no PWM or anything fancy, just…
Part Number: SG3524 Other Parts Discussed in Thread: DRV8251 , hi ,
I want to design a compressor that conforms to two different architectures
item1 have 3pin input,The middle tap of the coil is connected to 12v
item2 have 2pin input,
I want to use DRV8251…
Part Number: DRV8251 Other Parts Discussed in Thread: DRV8812 Hello, I have two questions.
Is there a mode where the H-bridge FET turns on due to residual charge in the capacitor of the booster circuit inside the driver when the power is off?
(Background…
Part Number: DRV8251 Is it possible to use a carbon film resistor, e.g. 0.2 Ohm 1W for a max. current of 1.9 A as stated in data sheet? It appears that metal film resistors (below 1 ohm) are inductive in nature.
Thanks,
Sudhir Gupta
Nathan,
The ripple will depend on your motor inductance. if you have other motors with different inductances, you can try and see if this 200mA is constant regardless of motor inductance.

Part Number: DRV8251 Howdy,
I'd like to replace an analog closed-loop motor current driver with DRV8251 or similar. Particularly interested in the internal current regulation, but require bandwidths in the 10s of kHz. Unfortunately, a couple of the…
