Simple sequencers for power supplies

19 May 2004 Power Electronics / Power Management Infrastructure Security Services & Risk Management

The ADM1085 to ADM1088 simple sequencers from Analog Devices provide an easy, yet powerful and flexible solution to the problem of power supply sequencing. They offer programmable time delays from 5 µs to several seconds and can be cascaded in a variety of ways to sequence multiple power supplies.

A choice of active-low or active-high outputs and push-pull or high voltage open-drain output stages ensures compatibility with a wide range of voltage regulators and DC-to-DC converters. The ADM1085 to ADM1088 are offered in 6-lead SC70 packages.

Key features: provide time delays between enabling of regulators; can be cascaded with regulators for multiple supply sequencing; power supply monitoring from 0,6 V; output stages: high voltage (up to 22 V) open-drain output (ADM1085/ADM1087), and push-pull outputs (ADM1086/ADM1088); fixed (5 µs typ) or capacitor adjustable time delays; enable input; low power consumption (15 µA); specified over -40 to +125°C temperature range.
