ISL8723 Power Sequencing Controllers

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. The ISL8723 has a low power standby mode when it .

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 bias.

ISL8723 Features
