second prototype built.
|
||||||
|
|
||||||
|
needs a couple of small fixes, but works much better.
|
||||||
|
|
||||||
|
fixes (from v0):
|
||||||
|
- an LDO replaces the zener diode as voltage reference
|
||||||
|
- the voltage reference (2.1V) is below common-mode input-voltage range
|
||||||
|
- USB-C plug tab mounting holes made larger
|
||||||
|
|
||||||
|
additions:
|
||||||
|
- quad op-amp instead of dual op-amp is used
|
||||||
|
- other 2 op-amp circuits are used to indicate over-voltage using an LED
|
||||||
|
- more compact dual common-cathode diodes are used
|
||||||
|
|
||||||
|
errors:
|
||||||
|
- no decoupling caps around LDO
|
||||||
|
- no clearance around USB-C receptacle mount holes, causing the non-plated hole to be fabbed plated, and shorting ground to internal layers
