Just want to get confirmation on wiring for these.
The Output are the pins not labeled “IN”, and those go to the device needing power?
Does this only need one wire off the microcontroller into the IN pin or does it need a GND? And thats into IN+?

Inputs
IN+ (TRIG+): This is the positive trigger input. Connected to JP3 pin 1 and BH1.
IN- (TRIG-): This is the negative trigger input. Connected to JP5 pin 1 and BH2, and is tied to GND.
Outputs
OUT+: This is the positive output. Connected to JP4 pin 2, JP2 pin 1, and BH3. It is also tied to V_BATT.
OUT-: This is the negative output. Connected to JP2 pin 2 and BH4.
Additional Connections
JP1: Connects to V_BATT and GND.
Q1 (FDS6630A): MOSFET used for switching.
R1: 10kΩ resistor connected between TRIG+ and the gate of Q1.
R2: 1MΩ resistor connected between the gate of Q1 and GND.
Thanks. Im new to this world (if that wasn’t obvious…)
Can you further explain the input connections? Wire from the controller pin to IN(+) and a wire from the controller GRN to IN(-)?
Is there a difference between the two sets of pins on each side? Two pins have a white box and the other set doesn’t.
Thanks for the help!
Also, can it be run on 3v logic, or does it need to be 5v to run a 5v device?
Any ideas?
Thanks for the help!
Per the data sheet (https://www.onsemi.com/download/data-sh … 630a-d.pdf), the FET requires a minimum of 3v on the gate to turn it on. Note that the drain-source resistance will be higher at a lower gate voltage so it will run hotter. You will need to derate the output current appropriately.
Thanks. Any ideas about the wiring in from the controller?
The digital output of your micro connects to IN+ (JP3p1, JP5p2, or BH1), called “TRIG+” in the schematic
The micro’s ground connects to IN- (J3p2, J5p1, or BH2) , called “GND” or “TRIG-” in the schematic
The load (negative lead if it is polarized) is connected to OUT- (JP4p2, JP2p1, or BH4)
The negative lead of the power supply for the load is connected to IN- (BH2 if the load draws more than an amp, J3p2, J5p1, or BH2 if an amp or less)
The positive lead of the power supply connects to the other terminal of the load. You can use OUT+ terminal BH3 if it is convenient or connect it directly if preferred. If the load is an amp or less, you can use JP4p1 or JP2p1 if it is convenient as well
Thanks, thats what I needed.
I looked at the smoke machine (that this will switch) and realized the wiring may not work with this setup now.
It’s wired to be directly connected to the battery and has leads for two switches (the other switch will be a mechanical switch, outside microcontroller use).
Im not sure if this will work now, and may need to rethink the setup. Maybe just a relay.
