Hai NXP Team,

we design Motor Controller using S32K311 Microcontroller With FS26 PMIC,

We config FS 26 PMIC as Direct Voltage from Battery voltage to VSUP pin. we don't used VBST connection so VBST_FB, VBST_ISL, VBST_ISH connected to GND as per datasheets.

Now only we get voltage VDIG =1.5V, VBOS =5.0V, VPRE =0V

what we do to get VPRE voltage ???

if this PMIC , will it support direct power supply to VSUP without Front end mode (without VBST) configuration

No,for these two parts had done OTP with the frond-end model which doesn't support this.
