μP Reset Circuits
____________ Applications Information
Interfacing to μPs with
V CC
Bidirectional Reset Pins
Since the RESET output on the MAX6328/MAX6348 is
open drain, these devices interface easily with micro-
V CC
V CC
processors (μPs) that have bidirectional reset pins,
such as the Motorola 68HC11. Connecting the μP
supervisor’s RESET output directly to the microcon-
troller’s (μC’s) RESET pin with a single pull-up resistor

allows either device to assert reset (Figure 1).
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 increas-
es, the maximum allowable pulse width decreases.
