The MAX6887/MAX6888 multivoltage supply supervisors
provide several voltage-detector inputs, one watchdog
input, and three outputs. Each voltage-detector
input offers a factory-set undervoltage and overvoltage
threshold. Manual reset and margin disable inputs offer
additional flexibility.
The MAX6887 offers six voltage-detector inputs, while
the MAX6888 offers four inputs. Output active-low RESET asserts
when any input voltage drops below its respective
undervoltage threshold or manual reset active-low MR is asserted.
Output active-low OV asserts when any input voltage exceeds its
respective overvoltage threshold. Monitor standard
supply voltages listed in the Selector Guide in the full datasheet.
The MAX6887/MAX6888 offer a watchdog timer with an
initial and normal timeout periods of 102.4s and 1.6s,
respectively. Watchdog output active-low WDO asserts when the
watchdog timer expires. Connect active-low WDO to manual reset
input active-low MR to generate resets when the watchdog timer
expires. RESET, OV, and WDO are active-low, open-drain
outputs.
The MAX6887/MAX6888 are available in a 5mm x 5mm
x 0.8mm, 16-pin thin QFN package and operate over
the extended -40°C to +85°C temperature range.
