Other Parts Discussed in Thread: ISO7740, ISO7840,
Hi,
I have some questions about the behavior of this device if voltage is applied to Viso:
1. What happens if the device is in 5V-5V mode -- VCC is 5V and Viso is generating, say 5V at 0A. What happens if 5.5V is applied to Viso? Will the chip use the 5.5V to power the digital signals? Will the internal converter circuitry use any current from the 5.5V supply?
2. Same situation as above, but VCC=0V, and an externally sourced ~5V is applied to Viso. Does the device consume power from this supply? Would it consume whatever the digital pins need, but nothing more?
Thank you,
Ishraq
