MAX16005ATE+T

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P21P22-P24P25-P26
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 moni-
tored 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 adjust-
ed 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 indepen-
dent 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.
