ISL8724 - Power Sequencing Controllers

Download the ISL8724 datasheet PDF. This datasheet also covers the ISL8723 variant, as both devices belong to the same power sequencing controllers family and are provided as variant models within a single manufacturer datasheet.

General Description

follow.

The four channel ISL8723 (ENABLE input), ISL8724 (ENABLE input) offer the designer 4 voltage control when it is required that all four rails are in minimal compliance prior to turn on and that compliance must be maintained during operation.

Key Features

  • Enables arbitrary turn-on and turn-off sequencing of up to four power supplies (0.7V to 5V).
  • Operates from 2.5V to 5V supply voltage.
  • Supplies VDD +5.3V of charge pumped gate drive.
  • Adjustable voltage slew rate for each rail.
  • Multiple sequencers can be easily daisy-chained to sequence an infinite number of independent voltages.
  • Glitch immunity.
  • Undervoltage lockout for each monitored supply voltage.
  • 30µA Sleep State (ISL872.

ISL8723, ISL8724 Power Sequencing Controllers The Intersil ISL8723 and ISL8724 are 4 channel sequencers controlling the on and off sequence of voltages with undervoltage supply fault protection and a “sequence completed” signal (RESET). For larger systems, more than 4 voltages can be sequenced by a simple connection of multiple IC's. These sequencers use an integrated charge pump to drive 4 external low-cost N-channel MOSFET switch gates above the IC bias voltage by 5.3V. These IC's can be biased from and control any supply from 2.5V to 5V and additionally monitor any voltage above 0.7V. Individual product descriptions follow.
