Tool/software:
Hi all,
The absolute maximum ratings of PFI pin of TPS3619 is -0.3V to (Vdd+0.3V).
When using this device is there any problem if a voltage (several volts) is applied to the PFI pin when VDD=0.0V (power off)?
In the application note below, when EN of DCDC in the first stage is Low, a voltage exceeding the absolute maximum rating is applied to PFI pin.
Using the TPS3619 With MSP430 Microcontrollers (Rev. B) (ti.com)
Referring to this circuit, I understand that there is no problem if some voltage is applied to the PFI pin when Vdd=0V.
Is this correct?
Best Regards,
Ryusuke
