Enpirion Power Datasheet ES1022SI Adjustable Quad Sequencer ES1022SI Datasheet NOT RECOMMENDED FOR NEW DESIGN The ES1022SI IC provides four delay adjustable Features sequenced outputs while monitoring an input voltage all Adjustable Delay to Subsequent EN Signal with a minimum of external components. Adjustable Delay to Sequence Auto Start High performance DSP, FPGA, P and various sub- systems require input power sequencing for proper Adjustable Distributed Voltage Monitoring functionality at initial power up and the ES1022SI Under and Overvoltage Adjustable Delay to Auto provides this function while monitoring the distributed Start Sequence voltage for over and undervoltage compliance. I/O Options: EN and SEQ EN This IC operates over the +3.3V to +24V nominal voltage range. It has a user adjustable time from UV and OV Voltage Compliance Fault Output voltage compliance to sequencing start via an external Pb-Free Plus Anneal Available (RoHS Compliant) capacitor when in auto start mode and adjustable time delay to subsequent EN output signal via external Applications resistors. Power Supply Sequencing Additionally, the ES1022SI provides I/O for sequencing System Timing Function on and off operation (SEQ EN) and for voltage window compliance reporting (FAULT) over the +3.3V to +24V nominal voltage range. Easily daisy chained for more than 4 sequenced signals. Altogether, the ES1022SI provides these adjustable features with a minimum of external BOM.
