Triple- Power Supply Monitor
GENERAL DESCRIPTION
The ADM9261 is a Multi-Supply Monitor IC which si-
multaneously monitors the three power supply voltages of
a pager system and outputs error signals if any of the sup-
ply voltages falls below an acceptable minimum value.
Analog Devices experience in the design of power supply
supervisory circuits is used to provide an optimum solu-
tion for the overall circuit in terms of cost, performance
and power consumption. Key features of the design in-
clude the incorporation of hysteresis and glitch immunity
into the comparators, which minimizes the possibility of
spurious triggering by noise spikes on the supplies being
monitored. Power supply voltages outside V
CC
can be
monitored without the need for input attenuators or other
components, and the current drain (including input cur-
rents of the monitoring circuits) is typically only 10
μ
A,
which imposes very little additional burden on the pager's
battery.
The ADM9261 is manufactured on one of Analog De-
vices proprietary BiCMOS processes, which also includes
high performance thin film resistors to achieve the accu-
racy required for the precision voltage reference and com-
parator trip points.
The ADM9261 is packaged in a space-saving μSOIC
package.
