Quad Voltage Up and Down Sequencer  
and Monitor with Programmable Timing  
ADM1186  
FEATURES  
GENERAL DESCRIPTION  
Powered from 2.7 V to 5.5 V on the VCC pin  
The ADM1186-1 and ADM1186-2 are integrated, four-channel  
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  
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.  
The ADM1186-1 and ADM1186-2 have four open-drain enable  
outputs, OUT1 to OUT4, that are used to enable power supplies.  
An open-drain power-good output, PWRGD, indicates whether  
the four VINx inputs are above their UV thresholds.  
Open-drain power-good output  
Open-drain sequence complete pin and bidirectional  
open-drain fault pin (ADM1186-1 only)  
APPLICATIONS  
DOWN  
A state machine monitors the state of the UP and  
pins  
Monitor and alarm functions  
DOWN  
on the ADM1186-1 or the UP/  
pin on the ADM1186-2  
Up and down power supply sequencing  
Telecommunication and data communication equipment  
PCs, servers, and notebook PCs  
to control the supply sequencing direction (see Figure 2). In the  
WAIT START state, a rising edge transition on the UP or  
DOWN  
UP/  
transition on the  
DONE state triggers a power-down sequence.  
pin triggers a power-up sequence. A falling edge
