Overview

Many of today’s high performance FPGA’s, microprocessors, DSP and industrial/embedded subsystems require sequencing of the input power. Historically this has been accomplished by: i) discretely using comparators, references & RC circuits; ii) using expensive programmable controllers; or iii) with low voltage sequencers requiring resistor drop downs and several high voltage optocoupler or level shift components.

  • Sequencing of four supplies, ICs, or subsystems
  • Independently programmable delays between open drain PWRGD flags (5.0 to 200ms)
  • ±10 to ±90V operation
  • Tracking in combination with Schottky diodes
  • Input supervisors including:
  • UV/OV lock out/enable
  • Power-on-Reset (POR)
  • Low power consumption, 0.4mA supply current
  • Available in a space saving 14-Lead SOIC package
