Intel ES1021QI

电源序列发生器1.5V ~ 5.5V200 µA

Overview

The IntelEnpirionES1021QI is an integrated 4-channel controlled-on/controlled-off power supply sequencer with supply monitoring, fault protection, and a ?sequence completed? signal (RESET). For larger systems, more thanfour supplies can be sequenced by simply connecting a wire between the SYSRESET pins of the cascaded ICs.

The ES1021QI uses a charge pump to drive four external low-cost NFET switch gates above the supply rail by 5.3V. External resistors provide flexible voltage threshold programming of monitored rail voltages. Delay and sequencing are provided by external capacitors for ramp-up and ramp-down.
