Other Parts Discussed in Thread: TIDA-00313,
We have designed an isolated voltage monitoring system as per TIDA-00313. Below I add a few doubts about this.
1)Do we require to connect +volt external power supply for INA226 Vs and ISO VCC1?. (Both VS and Vcc we connected to 4.7V Zener, will create a potential 43.3V difference between -48 and GND, Will this be enough for Vs ?)
2) The -VIN, +VIN, and Vbus Bottom resistor connections are Different in the TIDA design guide(fig2) and TIDA Schematic. which one is suitable for -48V.
3)Please find the attached Diagram for Review
