EVAL-ADM1186-2MBZ(Rev0) Datasheet PDF - Analog Devices

GENERAL DESCRIPTION
The ADM1186-1 and ADM1186-2 are integrated, four-channel voltage monitoring and sequencing devices. A 2.7 V to 5.5 V power supply is required on the VCC pin for power.
Four precision comparators, VIN1 to VIN4, monitor four voltage rails. All four comparators share a 0.6 V reference and have a worst-case accuracy of 0.8%. Resistor networks that are external to the VIN1, VIN2, VIN3, and VIN4 pins set the undervoltage (UV) trip points for the monitored supply rails.

FEATURES
   Powered from 2.7 V to 5.5 V on the VCC pin
   Monitors four supplies via 0.8% accurate comparators
   Digital core supports up and down supply sequencing
   Multiple devices can be cascaded (ADM1186-1)
   Four inputs can be programmed to monitor different voltage
      levels with resistor dividers
   Capacitor programmable supply sequence time delays
      and a timeout delay to 5% accuracy at 25°C
   Four open-drain enable outputs
   Open-drain power-good output
   Open-drain sequence complete pin and bidirectional
   open-drain fault pin (ADM1186-1 only)

APPLICATIONS
   Monitor and alarm functions
   Up and down power supply sequencing
   Telecommunication and data communication equipment
   PCs, servers, and notebook PCs
