Part Number: DRV8837 Other Parts Discussed in Thread: DRV8873 , DRV8212P , Hi team,
The customer would like to know are there any products with the DRV8873 that are fully P2P but offer better performance with lower price? Thanks.
Best Regards,
Cherry
Part Number: DRV8837 Other Parts Discussed in Thread: DRV8210P Hello team,
My customer want to use 1.8V to drive VCC of DRV8837C and I understand UVLO may be enabled when VCC<1.8V from below post. https://e2e.ti.com/support/motor-drivers-group/motor…
Part Number: DRV8837 Other Parts Discussed in Thread: DRV8838 , Hi Team,
Our customer noticed some spikes in the O rcad pspice simulation of DRV8837. He downloaded the Pspice model of DRV8837 from the product page. According to our customer,
I downloaded…
Part Number: DRV8837 Other Parts Discussed in Thread: DRV8212 Our piezoelectric motors operate at about 175 kHz. No problem for the 8837, which is spec'd at 250 kHz, but not enough current. The 8212 is only spec'd at 100 kHz- what can we expect if we try…
Part Number: DRV8837 Hi TI Technical Support Team,
I designed a board to contol hobby DC motors using DRV8837. Motor is 3-6V ~100rpm DC motor and draws around 150mA at full load. I am powering motor driver's Vm and Vcc from different 3.3V supply. I am…
Part Number: DRV8837 Other Parts Discussed in Thread: , DRV8212 Hi team,
Our customer wants a BDC driver with driver current greater than 3A. It's powered by 1S battery. Supply voltage is 3.5V-4.2V.
Due to the limitations of PCB, they used 2pcs DRV8837…
Part Number: DRV8837 Hi team,
Here's an issue from the customer may need your help:
During the test, the motor was replaced with a resistive load. When the input PWM was low, the OUT1 and OUT2 voltages could not be attributed to 0 V.
For example,…
Naveen,
Then that doesn't match any previous theories as the other drivers with much higher Rdson work fine. So, it appears we can rule out Rdson as the culprit.
Have you tried any of the other experiments recommended above with altering PWM duty…
Part Number: DRV8837 Other Parts Discussed in Thread: DRV8838 , DRV8210 Dear TI Technical Support Team,
I am designing a board that will be used to control direction and speed of 2xDC hobby motors (3-9V, 110RPM). Two of them can draw at most 250-300mA under…
Part Number: DRV8837 Other Parts Discussed in Thread: DRV8212P We use pairs of DRV8837 to drive 2-phase piezoelectric motors. They run near resonance, so capacitive and not a simple load. The peak currents can exceed plus and minus 2 amps (2 divisions…
