Hello,
I'm going to use the TIOS101 (no-LDO version) a low-side driver only. From the datasheet and discussions in this forum, it looks like that the VCC pin shall be powered even the voltage is not passed to the OUT pin (as it would be in high-side configuration). The application diagrams indicate that the VCC is used only to power the internal LDO (for applicable TIOS versions only) and the high-side driver. However because it is only illustrative diagram I'd like to ask following questions:
1. Can you please confirm that the TIOS101 cannot operate on low-side only mode with VCC_IN=5V and VCC= floating?
2. When both VCC_IN and VCC are needed, is it possible to operate the device from single 5V supply? The question arises from hypothesis that the minimum operating 7V voltage may be necessary to supply the internal LDO which is not needed in this case.
Thank you.
