==Systems==

===Voltage Sense===
We will have isolated voltage feedback. The voltage will be transmitted via a SPI ADC over a digital isolator.

===Current Limit===
To try to save our silicon, we have decided to try to limit the current using a sense resistor, a comparator, and some logic.

====Current Sense Resistor====
: Vendor - Digikey
: Vendor Part Number - FCSL90R010FERCT-ND
: Manufacturer - Ohmite
: Manufacturer Part Number - FCSL90R010FER
: Cost - $1.20

====Comparator====
: Vendor - Digikey
: Vendor Part Number - MAX932CSA+-ND
: Manufacturer - Maxim
: Manufacturer Part Number - MAX932
: Cost - $3.15
: [http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=MAX932CSA%2B-ND digikey]
: [http://pdfserv.maxim-ic.com/en/ds/MAX931-MAX934.pdf datasheet]

===Isolation===
We need to isolate the voltage sense, and the kick signals. This gives

* Sense (SPI)
** CLK - IN
** CS - IN
** Dout - OUT
* Trigger
** Chip - IN
** Kick - IN

So we need 4/1 in/out isolation

====Isolator====
: Vendor - Mouser
: Vendor Part Number - 634-SI8451AA-A-IS1
: Manufacturer - Si Labs
: Manufacturer Part Number - SI8451AA-A-IS1
: Cost - $2.43
: [http://www.mouser.com/ProductDetail/Silicon-Labs/SI8451AA-A-IS1/?qs=sGAEpiMZZMssyD0wnx/ymAX%252benCYBeiQHqVgI%252biUWPQ= mouser]
: [http://www.silabs.com/Support%20Documents/TechnicalDocs/Si845x.pdf datasheet]

===Power Supply===

The DC/DC converter needs to power the
* ADC - 5V 500uA
* Isolation - 5V 6mA
* Comparator - 5V 5mA (ballpark)
* Comparator Logic - 5V 5mA (7400 series logic, probably almost nothing)
* IGBT driver - 12V 10mA (be sure to bypass Vbat with 4.7uF ceramic, 47uF tantalum)

So lets shoot for around 5V 50mA LDO and around 12V 100mA DC/DC converter

==Solenoids==
See the [[SolenoidDevelopment| Solenoid Development]] page for more information. For logistics reasons, we may purchase a solenoid as we did last year and take it apart for use in our mounting apparatus.
