Part Number: DRV777 Hi team,
Here is an application of DRV777 want to double confirm with you.
I am using DRV777 for relay driver; but I have a diifferent logic voltage level but the same GND, which is 2.5V and 3.3V.
So if above application could…
Hi Dmitry,
VCOM can be as high as 16V, as described in the Recommended Operating Conditions.
Figure 4 is an example motor voltage. There are other voltage examples such as Page 9 "DRV777 can be used for driving 3V, 5V and 12V relays with similar…
Rick, do you know roughly how big of a voltage drop the DRV777 will cause if I power the 28-byj-48 stepper motor with 5V? I know for ULN2003, the saturation voltage is roughly 1V. Just wondering how much more efficient the DRV777 will be.
Thanks
Part Number: TPS7A47 Other Parts Discussed in Thread: DRV777 , Tool/software: Hi team,
My customer want to complete a ANYOUT on the fly configuration, referring to our sbva035a application note.
We are using a I2C expander to control the ANYOUT pin…
Hi SHH,
This is a 5 wire unipolar stepper, so the choices are limited. Below are three possible options assuming the system voltage is 5V.
The DRV8847 can be used in independent mode (see Table 6 of the datasheet). The inputs should be set to 0…
Hi Maksim,
The DRV8835 can be used to control the coils, but other options are available assuming you intend to drive more than one relay.
One alternative is the DRV777, which can control up to 7 devices using low side only.
Hi Sercan,
It is possible to connect the outputs in parallel, but there are still power limitations.
What is the desired current you seek? Do you need a VCLAMP pin? Do you need the serial interface?
We may other devices that are better suited for…
Hi user503335153,
You did not specify the relay voltage and currents. Assuming the relays are 12V and less than 140mA per relay, the DRV777 may fit your needs.
Hi Ishida-san,
What is the load current per solenoid?
The DRV777 may also work, but it depends on the load current per solenoid.
Other devices that could work are the DRV8804 and DRV8860, but the cost is much more. These two devices have higher…
