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 MAX6730A–MAX6735A µP supervisors are relative-
ly immune to short-duration falling V
(glitches). Small glitches on V
MAX6730A–MAX6735A, preventing undesirable reset
pulses to the µP. The Typical Operating Characteristics
