Single Channel Solenoid Driver

A prototype single channel solenoid driver was developed for testing.

It is contained in the driver-v0 folder.

We will have 3 manifolds with 8 of these in a row that need to be driven with 12V and signalled with a TTL line. All the manifolds will act in unison.

• 3 boards, 8 channels each
• 8 TTL inputs + GND
• 8 12V outputs

Octal Channel Driver

Dual Channel Complementary Driver

We will also have a pair of these valves that need to be driven by a single TTL line in opposition (if one is in state A the other should be in state B).

• LHDA1231415H
• https://www.theleeco.com/product/lhd-series-3-way-control-solenoid-valve/
• One TTL input + GND
• Two 12V complementary outputs

The solenoids should be driven with a high-side switch using a peak and hold circuit.
