MAX16000–MAX16007
Low-Voltage, Quad/Hex/Octal-Voltage
μP Supervisors
General Description
The MAX16000–MAX16007 are low-voltage, quad/hex/
octal-voltage μP supervisors in small TQFN and TSSOP
packages. These devices provide supervisory functions
for complex multivoltage systems. The MAX16000/
MAX16001/MAX16002 monitor four voltages, the
MAX16003/MAX16004/MAX16005 monitor six voltages,
and the MAX16006/MAX16007 monitor eight voltages.
The
MAX16000/MAX16001/MAX16003/MAX16004/
MAX16006 offer independent outputs for each
monitored voltage. The MAX16001/MAX16002/
MAX16004– MAX16007 offer a reset output that asserts
whenever any of the monitored voltages fall below their
respective thresholds or the manual reset input is asserted.
The reset output remains asserted for the reset timeout
after all voltages are above their respective thresholds
and the manual reset input is deasserted. The minimum
reset timeout is internally set to 140ms or can be adjusted
with an external capacitor.
All open-drain outputs have internal 30μA pullups that
eliminate the need for external pullup resistors. However,
each output can be driven with an external voltage up to
5.5V. Other features offered include a manual reset input,
a tolerance pin for selecting 5% or 10% input thresholds,
and a margin enable function for deasserting the outputs
during margin testing.
The MAX16001/MAX16002/MAX16004–MAX16007 offer
a watchdog timer that asserts
RESET
or an independent
watchdog output (MAX16005) when the watchdog timeout
period (1.6s typ) is exceeded. The watchdog timer can be
disabled by leaving the input open.
These devices are offered in 12, 16, 20, and 24-pin TQFN
and 16-pin TSSOP packages. These are fully specified
from -40°C to +125°C.
