Hi Thanos,
The TXB0108 is intended for logic voltage translation. In your case, you need a motor driver device. To give the short answer why this won't work for you, this device can only drive 20 uA of current, and a motor will typically need more…
Nagai-san,
How many channels are needed; what is the LED supply voltage?
For low current and low VOL, ULN2003V12 is a good choice, but it is 7 channel device.
Passer,
310mA is just slightly above the recommended maximum of 300mA. I have no schematic, but usage is very simple. The negative fan terminal goes to the SN75477 and the positive fan terminal goes to the 5V or 12V supply. The clamp pin goes to the higher…
Hello Leo,
Usually, even with the 1V drop, I see that relays typically work at a voltage slightly below the rated voltage. Do you have a specific relay you are looking at?
If you believe the dropout is too much, then yes, I would suggest using the TPL7407L…
Other Parts Discussed in Thread: ULN2003V12 , CD74HCT4067 , DRV8860 , TIDA-00117 Hi,
I need to drive a relay coil rated 12V DC coil voltage, 720 ohm coil resistance and 200mW switching power. Instead of using a driver for each and every relay, I want to…
Hi,
i don't think using a DC/DC converter is the right way for this. You can use for example the ULN2003v12 http://www.ti.com/product/uln2003v12 to interface the 12V environment.
Coulon,
We don't have single drivers. However, the ULN2003V12 (7 channel driver) can also do the job at a lower cost.
You could go discrete components. This darlington transistor will need a 2.7k ohm base resistor and a diode like 1N4001 to make a…
