3-Pin, Ultra-Low-Power SC70/SOT
μP Reset Circuits
Since the
RESET
output on the MAX6328/MAX6348 is
open drain, these devices interface easily with micropro-
cessors (µPs) that have bidirectional reset pins, such as
the Motorola 68HC11. Connecting the µP supervisor’s
RESET
output directly to the microcontroller’s (µC’s)
RESET
pin with a single pull-up resistor allows either
device to assert reset (Figure 1).

INPUT
Negative-Going V
CC
Transients
In addition to issuing a reset to the µP during power-up,
power-down, and brownout conditions, these devices are
relatively immune to short-duration, negative-going V
CC
transients (glitches).
The
Typical Operating Characteristics
show the Maxi-
mum Transient Duration vs. Reset Threshold Overdrive
graph, for which reset pulses are not generated. The
graph shows the maximum pulse width that a negative-
going V
CC
transient may typically have when issuing a
reset signal. As the amplitude of the transient increases,
the maximum allowable pulse width decreases.
