ADSP-2126x SHARC Processor Hardware Reference
• Power low monitor
• Backup battery switching
The part number series for supervisory circuits from Analog Devices are:
• ADM69x
• ADM70x
• ADM80x
• ADM1232
• ADM181x
• ADM869x
A simple power-up reset circuit is shown below, using the
ADM809-RART reset generator. The ADM809 provides an active low
RESET
signal whenever the supply voltage is below 2.63 V. At power-up, a
240 ms active reset delay is generated to give the power supplies and oscil-
lators time to stabilize.
Another part, the ADM706TAR, provides power on
RESET
and optional
manual
RESET
. It allows designers to create a more complete supervisory
circuit that monitors the supply voltage. Monitoring the supply voltage
allows the system to initiate an orderly shutdown in the event of power
failure. The ADM706TAR also allows designers to create a watchdog
timer that monitors for software failure. This part is available in an
eight-lead SOIC package.
shows a typical application circuit
using the ADM706TAR.
