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 MAX6730A–MAX6735A P supervisors are relative-
ly immune to short-duration falling VCC_ transients
(glitches). Small glitches on VCC_ are ignored by the
MAX6730A–MAX6735A, preventing undesirable reset
pulses to the P. The Typical Operating Characteristics
show Maximum VCC_ Transient Duration vs. Reset
