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 µP. Connect a 10kΩ resis-
tor between RST and the µP’s reset I/O port to prevent
logic contention (Figure 5).
The MAX6730–MAX6735 µP supervisors are relatively
immune to short-duration falling V
es). Small glitches on V
MAX6730–MAX6735, preventing undesirable reset
pulses to the µP. The Typical Operating Characteristics
show Maximum Transient Duration vs. Reset Threshold
