FIGURE 5-10: BROWN-OUT SITUATIONS
5.1.5
PIC17C75X devices have an on-chip Brown-out Reset
circuitry. This circuitry places the device into a reset
when the device voltage falls below a trip point (BV
This ensures that the device does not continue pro-
gram execution outside the valid operation range of the
device. Brown-out resets are typically used in AC line
applications or large battery applications where large
loads may be switched in (such as automotive).
A configuration bit, BODEN, can disable (if clear/pro-
grammed) or enable (if set) the Brown-out Reset cir-
cuitry. If V

greater than parameter D035, the brown-out situation
will reset the chip. A reset is not guaranteed to occur if
V
The chip will remain in Brown-out Reset until V
above BV
and will keep the chip in reset an additional 96 ms. If
V
running, the chip will go back into a Brown-out Reset
and the Power-up Timer will be initialized. Once V
rises above BV
96 ms time delay. Figure 5-10 shows typical Brown-out
situations.
In some applications the Brown-out reset trip point of
the device may not be at the desired level. Figure 5-8
and Figure 5-9 are two examples of external circuitry
that may be implemented. Each needs to be evaluated
to determine if they match the requirements of the
application.
