Brown-Out Detection
The Brown-Out Detection (BOD) circuit monitors that the V

low the trigger level for a minimum time, t
above the trigger level again.

For characterization data on t
by a programmable BODLEVEL setting, see
Table 8-2.
Note:
The BOD circuit has 3 modes of operation:
• Disabled: In this mode there is no monitoring of the V
• Enabled: In this mode the V
