GENERAL DESCRIPTION
The ADM1184 is an integrated, 4-channel voltage-monitoring
device. A 2.7 V to 5.5 V power supply is required on the VCC pin
to power the device.
Four precision comparators monitor four voltage rails.
Each comparator has a 0.6 V reference with a worst-case
accuracy of 0.8%. Resistor networks that are external to the
VIN1, VIN2, VIN3, and VIN4 pins set the trip points for
the monitored supply rails.
The ADM1184 has four open-drain outputs. OUT1 to OUT3
can be used to enable power supplies, and PWRGD is a
common power-good output.
Figure 1.
OUT1 to OUT3 are dependent on their associated VINx input
(that is, VIN1, VIN2, or VIN3). If a supply monitored by VINx
drops below its programmed threshold, the associated OUTx pin
and PWRGD are disabled.
PWRGD is a common power-good output indicating the status
of all monitored supplies. There is an internal 190 ms (typical)
delay associated with the assertion of the PWRGD output. If
VIN1, VIN2, VIN3, or VIN4 drops below its programmed
threshold, PWRGD is deasserted immediately.
The ADM1184 is available in a 10-lead mini small outline
package (MSOP).
