Applications Information
Interfacing to Ps with Bidirectional
Reset Pins
Microprocessors with bidirectional reset pins can inter-
face directly with the open-drain RST output options.
However, conditions might occur in which the push-pull
output versions experience logic contention with the
bidirectional reset pin of the P. Connect a 10k
resis-
tor between RST and the P’s reset I/O port to prevent
logic contention (Figure 5).
Falling VCC Transients
The MAX6730–MAX6735 P supervisors are relatively
immune to short-duration falling VCC_ transients (glitch-
es). Small glitches on VCC_ are ignored by the
MAX6730–MAX6735, preventing undesirable reset
pulses to the P. The Typical Operating Characteristics
show Maximum Transient Duration vs. Reset Threshold
