Change Log

Rev 1.0

• TDFN14 footprint has mirrored pin mappings

  • Resolution: Rev 1.1

Rev 1.1

• Fixed TDFN pinout

• A challenger vehicle might not draw as much current, so the current sense amplifier should have a different gain. Also, it might be better to use a Hall effect sensor to reduce power consumption.

• Use a smaller transformer?

• Buck instead of LDO

• Consider instrumentation amplifier rather than differential amplifier?

• Filtering for the current sense amplifier? Common mode vs. differential mode

• Integrated current sense ICs? Not sure if they perform better

• Use connectors similar to these for BPS testing?

  • Has an internal switch to disconnect the signal from the rest of the circuit

  • I think it would be cool, but not really necessary…

• Is the buffer necessary?
