Enpirion Power Datasheet ES1021QI Power Sequencing Controller ES1021QI Datasheet The Altera Enpirion ES1021QI is an integrated 4-channel Features controlled-on/controlled-off power-supply sequencer with supply monitoring, fault protection and a sequence Enables Arbitrary Turn-on and Turn-off Sequencing of ). ES1021QI uses a patented, Up to Four Power Supplies (0.7V to 5V) completed signal (RESET micropower 7x charge pump to drive four external low- Operates From 1.5V to 5V Supply Voltage cost NFET switch gates above the supply rail by 5.3V. Supplies V +5.3V of Charge Pumped Gate Drive DD These ICs can be biased from 5V down to 1.5V by any Adjustable Voltage Slew Rate for Each Rail supply. Multiple Sequencers Can be Daisy-Chained to Sequence ES1021QI has two groups of two channels, each with its an Infinite Number of Independent Supplies independent I/O. It is ideal for voltage sequencing into Glitch Immunity redundant capability loads. All four inputs must be satisfied before turn-on, but a single group fault is Undervoltage Lockout for Each Supply ignored by the other group. Active Low ENABLE Input External resistors provide flexible voltage threshold Dual Channel Groupings programming of monitored rail voltages. Delay and QFN Package sequencing are provided by external capacitors for Pb-free (RoHS-compliant) ramp-up and ramp-down. Additional I/O is provided for indicating and driving Applications state in various configurations. the RESET Graphics Cards For volume applications, other programmable options FPGA/ASIC/Microprocessor/PowerPC Supply and features are available.
