Peak-And hold-Driver
About the Peak-And hold-Driver PCB
Peak-And hold-Driver is an open source PCB design by Tjeerdie, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 100.1 × 50 mm, with 112 components from 35 distinct parts.
Other key parts include the 74HC32, LM2901, 74HC74, LTC6992 and LM340. By type, the board carries 45 resistors, 20 transistors, 19 diodes, 14 capacitors, 8 ICs and 2 connectors.
From the project
Peak and hold injector driver for low-Z injectors.
I still do encourage everyone to use resistors if possible because the results are good and resistors have less components that can fail This design is specific to work with LPG injectors but could be used for any other low-Z injectors like TBI type and other high flow injectors. It could even be used for any coil type actuator like relays or valves
The board is designed in Kicad. So to see the schematic or to adjust the design to your liking open the Kicad project.
