The GL3523S is a highly cost-effective and flexibly configurable USB3.1 Gen 1 hub controller with on-chip integration of USB Type-C functions. It is compliant with the USB3.1 Gen 1 specification, and fully backward-compatible with HS/FS/LS hosts and devices. The GL3523S achieves high data throughput and power efficiency with the industry’s lowest 0.86W power consumption when all four downstream ports are operating with SuperSpeed devices and 10mW at suspend state. It integrates 5V to 3.3V and 5V to 1.2V regulators to save the added BOM cost for customers and provides flexible power design.
In addition, it includes advanced fast-charging, supporting Battery Charging v1.2 (CDP/DCP/ACA-Dock), Apple 1A/2.4A, Samsung Galaxy mode and QC2.0. Beyond these features, GL3523S incorporates patented Smart Power Management that can dynamically switch the mode of the downstream ports to ensure the quality of flow. GL3523S can be configured according to customers’ needs such as disabling specific downstream ports, compound device setting, and customised GPIO/LED usages. With USB Type-C functions integrated, GL3523S is well-suited for Type-C applications without external switches and CC controllers needed. In Type-C applications, GL3523S not only provides expansion for USB ports but also features complete functions of CC controllers, including handshaking for attaching, discovering/configuring VBUS (USB Type-C™ current modes up to 3A@5V), and configuring/providing VCONN power. Available packages are 4 downstream ports in BGA144/QFN88 and 2 downstream ports in QFN76.
