48.6.1 Brown-Out Detectors (BOD) Characteristics

Table 48-7. BOD33 Characteristics with BOD33.VREFSEL = 0
Symbol	Parameters	Conditions	Min.	Typ.	Max.	Unit
VBOD+ ⁽²⁾	BOD33 high-threshold level	BOD33.LEVEL = 8	1.74	1.76	1.78	V
		BOD33.LEVEL = 9	1.77	1.79	1.81	V
		BOD33.LEVEL = 39	2.79	2.84	2.89	V
		BOD33.LEVEL = 48	3.11	3.18	3.20	V
VBOD- / VBOD ⁽²⁾	BOD33 low-threshold Level	BOD33.LEVEL = 8	1.67	1.70	1.71	V
		BOD33.LEVEL = 9	1.71	1.74	1.75	V
		BOD33.LEVEL = 39	2.74	2.78	2.80	V
		BOD33.LEVEL = 48	3.04	3.09	3.11	V
-	Step size			34		mV
VHys	Hysteresis (VBOD+ - VBOD-) BOD33.LEVEL = 0x0 to 0x3F		30	-	180	mV
Tstart	Startup time ⁽¹⁾	time from enable to RDY	-	3.2	-	us

Note:

The values are based on simulation, and are not covered by test or characterization.
With BOD33.VREFSEL = 0 and no hysteresis configured, BOD levels can be given as:
Vbod+=Vbod-=1.43+Bod setting*Step_size.

Note:

These are based on simulation. These values are not covered by test or characterization.
With BOD33.VREFSEL = 1 and no hysteresis configured, BOD levels can be given as:
Vbod+=Vbod-=1.17+Bod setting*Step_size.
