PWM will be better choice than series regulator for holding the solenoid. As this is simple requirement, hence it could be pretty done well with all analog circuits without needing of any programable MCU. There will be two presets, one for the initial delay 100-300ms and other one for setting duty cycle of the PWM after energizing the solenoid. However, as the battery voltage drops from certain voltage when battery is fully charged, so a voltage feedback mechanism is also needed in order to keep the holding current constant. Also if needed, a slow blow type current sense protection could be implemented. Latching type, when average current exceeds certain current, this will cutoff the output and normal operation will be activated again when a reset button is pressed. Interesting schematic design. I would design this in KiCad. $200 my service charge + $20 freelancer's commissions. Thanks

Hi I’d be glad to help you design a custom solenoid driver module to replace your timer relay setup. I have over 12 years of experience in high-current power electronics, motor/solenoid drivers, and PCB design, and I’ve built similar circuits that combine kick-start overdrive with safe holding current. My approach: Kick + Hold Control: Apply full 18 V “kick” for 100–300 ms, then automatically drop to safe holding current using PWM regulation. Protection Features: Integrate flyback diode/TVS suppression, overcurrent sensing, and thermal cutoff to protect the solenoid and driver. Timing & Control: Adjustable kick duration, optional hold duration, and lockout until the trigger switch is released. Rugged Design: Use MOSFET-based switching for high efficiency, rated for >15 A continuous with safe margins. Deliverables: Complete schematic, BOM (with readily available parts), and PCB layout (KiCad or EasyEDA). I understand your current setup is working with a timer relay but relies on a fuse to prevent damage. My design will eliminate this weakness by using active protection and current limiting, making the system safer and more reliable for repeated use. I can also recommend suitable MOSFETs, gate drivers, and thermal design strategies to ensure long-term durability. If you share your current prototype details, I can get started immediately and provide a draft schematic for review. Best regards, Ting
