DESCRIPTION
The LTC®2928 is a four channel cascadable power supply sequencer and high accuracy supervisor. Sequencing thresholds, order and timing are configured with just a few external components, negating the need for PC board layout or software changes during system development. Multiple LTC2928s may be easily connected to sequence an unlimited number of power supplies.
