Part Number:DRV110EVM
In reply to Costin Cazana:
I'm using the DRV110EVM setup above with a TTL signal generator (1 Hz) into the Enable pin. I'm trying to drive a bank of six 12vdc solenoid valves (29 ohm each) connected in parallel (4.8 ohm to the DRV110). I can barely drive one valve with 14vdc supply. I tried using a Solid State Relay (SSR) but its turn-on and turn-off speed is too slow to effectively pass the PWM pulses.
What must I do to drive at least two or three of my solenoid valves? I have attached images of my setup. Please let me know if you cannot see them.
Is it possible to use a faster SSR to drive the bank of six valves?
Thanks for your help,
Ken
