MAXIM MAX6888METE

The MAX6887/MAX6888 provide several supply-detector inputs, one watchdog input, and three outputs for powersupply monitoring applications. The MAX6887 offers six voltage-detector inputs, while the MAX6888 offers four. Each voltage-detector input offers both an undervoltage and overvoltage threshold. The undervoltage and overvoltage thresholds are factory-set for monitoring standard supply voltages (see the Selector Guide). Inputs in the Selector Guide that contain “Adj” allow an external voltage-divider to be connected to set a user-defined threshold.

• 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 RESET asserts when any input voltage drops below its respective undervoltage threshold or manual reset MR is asserted.
• Output OV (with right arrow above) 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, opendrain outputs.
• The MAX6887/MAX6888 are available in a 5mmx5mmx0.8mm, 16-pin thin QFN package and operate over the extended -40℃ to +85℃ temperature range.
