ISL8723 Overview
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 pleted” 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...
ISL8723 Key Features
