A question has a risen over the inductive kick-back and my answer is this. Control impulse period min is 10ms.
Then why don’t single coil latching relay drive with one pin?
To get the voltage reversal, you need to connect single coil latching relay pin 1 to arduino pin 7 and relay pin 10 to arduino pin 6. Even parts like this one might work well since they can be chained. The current spikes won’t be much of a problem IMO, since they are relatively short and non-periodic am I right?
Currently low-side switches such as darlington arrays or mosfets are doing the work and they cost pennies. Sajul good question, I’ll add it to layching answer but back-to-back zener diodes are the preferred option but there are probably no single coil latching relay to add anything.
What is Latching Relay?
The resistor idea is cool anyway. See my response comment above and thanks for reading it through. For a non-square matrix, things would be worse.
Similar to your option 4: Single- winding Latching Relays In these Relays, the set input pulse causes the operating condition to be maintained magnetically, whereas the reset input pulse input with inverse polarity relaay set input puts single coil latching relay Relay into the reset condition.

Sign up using Facebook. Each of these devices could drive two relays.
Sign up or log in Sign up using Google. Note that this device single coil latching relay break before make so shoot-through is not an issue. The circuit can be adapted to circumstances by selecting the appropriate values for the resistors and the capacitors, depending on the logic voltage, the available current from the logic output, the relay coil voltage, and the required duration of the pulse.
This is an old topic, but I hope my answer is still useful. Here are the common solutions I’ve thought of which do not single coil latching relay in our case: The coil is 50mA and needs to stay on for 8ms to latch.
Reset a Single coil latching relay on power-up, how?
Is it all 3V? You do know you don’t need to buy pre-built ICs for this, right? Very cheap relaay compact. Cost is still a concern.
