Simple Sequencer® Provides a Flexible, Cost-Effective Solution for Power Supply Sequencing
Today's complex systems often require two to four voltage rails to be sequenced. These voltages need to be monitored accurately and then powered up in the correct sequence while ensuring the correct timing delay between each of the voltage rails. If the power supply voltage drops below the threshold, the system can shut down, potentially causing a loss of data. The ADM6820 and ADM1086 power supply sequencing ICs can accurately and reliably sequence power rails. The outputs are asserted after programmable turn-on delays, enabling the ADP121 and ADP130 linear regulators in the desired sequence. The thresholds are established by resistor ratios; the delay is established by a capacitor. To learn more about ADI's family of linear regulators, go to www.analog.com/LDO.

*Denotes quantities between 1000-4999. Single and Multichannel Voltage Supervisors and Watchdog Timers Deliver Increased Accuracy and System Reliability The number of voltage rails in complex systems has increased dramatically in recent years. A single board may comprise microprocessors, FPGAs, and ASICs, along with analog and digital circuit elements. Monitoring of the ever increasing number of voltage rails is fundamental for the safe, robust, and reliable operation of the system over its lifetime. As the number of voltage rails increases, the probability of a fault occurring increases proportionately. ADI's family of high accuracy multivoltage monitors offer a simple, precise, cost-efficient method of ensuring reliable operation in complex multivoltage systems, while dramatically reducing required board space.
