Done:
-Power distribution board is now split into front and rear
-A power path channel for power supply is implmented
-Reverse polarity protection for the power supply channel is added
-Aux battery over current protection is added
-Back to back MOSFET is changed
-Protected and unproteced rail is now determined bt firmware
-Removed unprotected rail
-Added calculations for new under and over voltage condiction for the
power path, including AUX and DCDC
-Added calculation for AUX battery fault delay time
To do:
-Validify AUX over current protection
-Validify power supply reverse polarity protection
-Add AUX battery charger
-Concider switching connector and load switch for higher current rating
* Schematic changes
RearPowerDistribution
-Rear Power Distribution now have multiple rear light load switch and
connectors to power each rear light individualy
-Changed the high current load switch to a lower 15A rating single
channel
-Added a medium current load switch with 4.5A rating
-Reassigned loads to matching load switchs that can supply the load with
required current based on MSXIV_PowerBuget Sheet
-Reassigned load switch pin-outs according to the load reassignment
-Added multi-channel schamatics for repeated design like load switch and
ADC
-Added one extra I/O expander for enabling lights
-Deleted calculation notes, it is now recorded within a DOC
-Added a MUX for current sense selection
-Finalized power supply reverse polirity protection
-Finalized AUX over current protection
-AUX over current comparitor comes with a latching feature witch can
keep the AUX circuit open during over current event
-Hysteresis not implemented
-A jumper to 3V3 is also connected to the latching enable pin,
populate if the feature is not good, it will function as a
comparitor
FrontPowerDistribution
-None
Libery alternation
-Added symbols and footprints for Infineon smart loadswitchs of 15A,11A, and 4.5A
-Added symbol and footprint for Latching comparitor
* Rear Power Distribution
-Changed load connectors to avoid misconnection on major loads:
-BMS
-Motor Interface
-Rear Lights
Added libs
-IC COMP TTL/CMOS 1 CHAN SC70-6
-IC LOAD SWITCH BTS 7200-2EPA PG-TSDS0-14-1
-IC LOAD SWITCH BTS 70401EPA PG-TSDS0-14-22
-IC LOAD SWITCH BTS 70041EPPXUMA1CT-ND_1
-IC LOAD SWITCH BTS 70081EPPXUMA1
-RES SMD 48.7 Kohms 0.1%
-RES SMD 11.3 Kohms 0.1%
* Realocated the load switch and connector to one sheet
* -Fixed symbol and footprint
-Fixed Schematic nets
-Started PCB layout
* generated gerber files and finished pcb layout
