General Description
The MAX6887/MAX6888 multivoltage supply supervi-
sors provide several voltage-detector inputs, one watch-
dog 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 RESET asserts
when any input voltage drops below its respective
undervoltage threshold or manual reset MR is asserted.
Output OV asserts when any input voltage exceeds its
respective overvoltage threshold. Monitor standard
supply voltages listed in the
Selector Guide.
The MAX6887/MAX6888 offer a watchdog timer with an
initial and normal timeout periods of 102.4s and 1.6s,
respectively. Watchdog output WDO asserts when the
watchdog timer expires. Connect WDO to manual reset
input 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.
