Brown Out Detector
The brown out detector circuit is used to detect voltage drops. If a short glitch occurs in the
power, this circuit ensures that the processor resets properly rather than operating randomly.
The brown out detector must be set to the same voltage as the circuit voltage (Vcc) - 3.3V or 5V.
For 3.3V operation, jumper JP2 must be removed (jumper open) and for 5V operation it must be
closed.
Voltage Operating Voltage Hysterisis
5 Volts 4.5 Volts 200 mV
3.3 Volts 2.9 Volts 200 mV
These values are approximate and may vary with temperature and other factors.
