DESCRIPTION
The DS1836 MicroManager performs three vital system functions. First a precision temperature-
compensated reference and comparator circuit monitor the status of the voltage on V
CC
and when an out-
of-tolerance condition is detected, an internal power-fail signal is generated which forces the reset active.
If V
CC
continues to degrade it switches to the battery supply when V
CC
drops below 3.8 volts (2.6 volts
for 3.3-volt versions). When V
CC
exceeds 3.9 volts (2.8 volts for 3.3-volt versions); V
OUT
will again be
supplied from V
CC
. Reset will remain active for 350 ms after V
CC
returns to an in-tolerance condition.
Lastly, the DS1836 supports a sense input that sends a non-maskable interrupt whenever the sense input
drops below 1.25 volts.

Is it better for the crystal oscillator trace to transition from thick to thin to the chip or to keep it the same width as the chip pins?
As the title says! I hope an expert can give a theoretical answer. Thank you! Is it better to make the crystal trace as thick as possible or to keep it consistent? If it is consistent, it cannot be to...
