MAX6730A–MAX6735A
Detailed Description
Supply Voltages
The MAX6730A–MAX6735A microprocessor (P) super-
visors maintain system integrity by alerting the P to fault
conditions. The MAX6730A–MAX6735A monitor one to
three supply voltages in P-based systems and assert
an active-low reset output when any monitored supply
voltage drops below its preset threshold. The output
state remains valid for VCC1 or VCC2 greater than +0.8V.
Threshold Levels
The two-letter code in the Reset Voltage Threshold
Suffix Guide (Table 1) indicates the threshold level
combinations for VCC1 and VCC2.
Reset Output
The MAX6730A–MAX6735A feature an active-low reset
output (RST). RST asserts when the voltage at either
VCC1 or VCC2 falls below the voltage threshold level,
VRSTIN drops below its threshold, or MR is driven low
(Figure 1). RST remains low for the reset timeout period
(Table 2) after VCC1, VCC2, and RSTIN increase above
their respective thresholds and after MR releases high.
Whenever VCC1, VCC2, or RSTIN go below the reset
threshold before the end of the reset timeout period, the
internal timer restarts. The MAX6730A/MAX6732A/
MAX6734A provide an open-drain RST output, and the
MAX6731A/MAX6733A/MAX6735A provide a push-pull
RST output.

**Standard versions are shown in bold and are available in a
D3 timeout option only. Standard versions require 2500-piece
order increments and are typically held in sample stock. There
is a 10,000-piece order increment on nonstandard versions.
Other threshold voltages may be available; contact factory
for availability.
