VDDS Brown-out Detector (BOD)
External regulator mode
Rising threshold 1.64 V
VDDS Brown-out Detector (BOD), before initial boot

Falling threshold 1.75 V
VDDS Brown-out Detector (BOD)
External regulator mode
Falling threshold 1.63 V
(1) For boost mode (VDDR =1.95 V), TI drivers software initialization will trim VDDS BOD limits to maximum (approximately 2.0 V)
(2) Brown-out Detector is trimmed at initial boot, value is kept until device is reset by a POR reset or the RESET_N pin
