Enpirion Power Datasheet ES1020QI Power Sequencing Controller ES1020QI Datasheet The Altera Enpirion ES1020QI is an integrated 4-channel Features controlled-on/controlled-off power-supply sequencer Enables Arbitrary Turn-on and Turn-off Sequencing of with supply monitoring, fault protection and a sequence Up to Four Power Supplies (0.7V to 5V) ). For larger systems, more than completed signal (RESET four supplies can be sequenced by simply connecting a Operates From 1.5V to 5V Supply Voltage wire between the SYSRESET pins of cascaded ICs. The Supplies V +5.3V of Charge Pumped Gate Drive DD ES1020QI uses a patented, micropower 7x charge pump to Adjustable Voltage Slew Rate for Each Rail drive four external low-cost NFET switch gates above the Multiple Sequencers Can be Daisy-Chained to Sequence supply rail by 5.3V. These ICs can be biased from 5V an Infinite Number of Independent Supplies down to 1.5V by any supply. Glitch Immunity External resistors provide flexible voltage threshold Undervoltage Lockout for Each Supply programming of monitored rail voltages. Delay and sequencing are provided by external capacitors for Low ENABLE Input ramp-up and ramp-down. QFN Package Additional I/O is provided for indicating and driving Pb-free (RoHS-compliant) the RESET state in various configurations. Applications For volume applications, other programmable options and features are available.
