Frequently Asked Questions
What is the maximum current the LM3526MX-H/NOPB can supply per USB port?
The LM3526MX-H/NOPB provides a current limit of 500mA per port, which complies with the USB 2.0 specification for bus-powered devices. When over-current is detected, the switch automatically shuts off to protect both the host and the connected peripheral.
What package does the LM3526MX-H/NOPB come in and what are its dimensions?
The LM3526MX-H/NOPB is housed in a compact SOT-23-6 (MX) surface-mount package. This small footprint makes it ideal for space-constrained PCB designs such as laptops, tablets, and USB hubs where board area is at a premium.
What are typical applications for the LM3526MX-H/NOPB?
Typical applications include USB hubs, notebook and desktop computers, docking stations, and embedded systems requiring controlled USB power distribution. The dual-channel architecture allows independent power management of two USB downstream ports simultaneously, simplifying host controller design.
How do I enable or disable the USB ports on the LM3526MX-H/NOPB?
Each port on the LM3526MX-H/NOPB is controlled by an active-high enable input. Driving the EN pin high turns on the corresponding power switch, while pulling it low turns it off. This allows the host microcontroller or USB hub controller to independently control power to each connected USB device.
