Overview

The SLG7SQ47664 is a compact, dual-channel voltage sequencer designed for precise control in multi-supply systems. It features configurable time delays and trigger thresholds, ensuring accurate power-up sequencing for voltage regulators and DC/DC converters. With open-drain output stages on PIN9 and PIN10, this device offers flexible compatibility with various logic levels and is configurable via I2C. For custom configurations, visit the GreenPAK website.

PIN9 is an open-drain output stage, with active high (ENOUT) and PIN10 has an active low (ENOUT) output. Both have open-drain output stages that can be pulled up to voltage levels as high as VDD + 0.5V through an external resistor, which increases compatibility with enabling input logic levels of different regulators and converters. There is a dedicated enable pin allowing the outputs to be controlled externally.

Both delay time and trigger threshold can be configured via I 2C. The default delay time is configured to 10.25ms but can be configured between 976.56µs – 125ms. The default threshold is set to 608mV but can be configured between 32mV and 2.016V in 32mV steps. The IC is housed in a 1.6mm x 1.6mm STQFN package for seamless integration into any board design.
