Brown-Out Detectors (BOD) Characteristics

Table 1. 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
Notes:
  1. 1.The values are based on simulation, and are not covered by test or characterization.
  2. 2.With BOD33.VREFSEL = 0 and no hysteresis configured, BOD levels can be given as:

    Vbod+=Vbod-=1.43+Bod setting*Step_size.
