Keep Microprocessors DSPs Self-Reliant with ADI's Watchdog Supervisory Circuits
icroprocessors need reset when code execution errors occur when supply voltages fall invalid levels. watchdog function detect code execution errors monitoring frequent logic transitions microprocessor's output pin. transition detected within certain time period, watchdog circuit will initiate reset signal that will take microprocessor invalid state.
ADI's broad portfolio watchdog supervisory devices save embedded systems from dangerous situations. full family devices offers both high accuracy best class packaging. Many devices also feature power fail detection comparator that asserts active signal when unregulated power supply voltage falls below predetermined level. This power fail output used generate nonmaskable interrupt, which allows microprocessor implement shutdown procedure before power lost.
