Product Overview

The LTC2928IUHF#PBF is a 4-channel cascadable Power Supply Sequencer and High Accuracy Supervisor feature over-voltage and fault indication. 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. Sequence outputs control supply enable pins or N-channel pass gates. Precision input comparators with individual outputs monitor power supply voltages to 1.5% accuracy. Supervisory functions include under-voltage and over-voltage monitoring and reporting as well as µP reset generation. RST may be forced high to complement margin testing. Application faults, whether internally or externally generated, can shut down all controlled supplies. The type and source of faults are reported for diagnosis.
  • Easily configure power management without software
  • Cascades for additional supplies
  • Staged supply sequencing with adjustable time positions
  • Fault event reporting with diagnostics
  • Selectable system shutdown on fault
  • Configurable under-voltage and over-voltage thresholds
  • Charge pumped enable pins drive N-channel MOSFETs
  • 1.5% Under-voltage monitor accuracy
