Frequently Asked Questions
What is the maximum current rating per port for the LM3526M-H/NOPB?
The LM3526M-H/NOPB supports up to 500mA per USB port channel. It provides independent overcurrent protection on each of its two output channels, automatically shutting down the affected port when the current limit is exceeded to prevent damage to the host system and connected devices.
What protection features are built into the LM3526M-H/NOPB?
The LM3526M-H/NOPB integrates multiple protection mechanisms including overcurrent protection (500mA limit), thermal shutdown, transient protection, and under-voltage lockout (UVLO). An open-drain fault flag output signals the host controller whenever a fault condition is detected on either USB port.
What are typical applications for the LM3526M-H/NOPB?
This device is widely used in USB hubs, laptop and desktop USB host ports, embedded computing boards, and industrial control systems. It is also suitable for automotive infotainment USB ports, set-top boxes, and any application requiring switched and protected 5V USB bus power with dual-channel control.
What package does the LM3526M-H/NOPB come in, and is it RoHS compliant?
The LM3526M-H/NOPB is available in an 8-pin Small Outline (SOIC) package, JEDEC code R-PDSO-G8. It is fully RoHS compliant and Pb-free (JESD-609 code e3), making it suitable for green and environmentally regulated manufacturing processes.
What is a compatible or alternative part to the LM3526M-H/NOPB?
Compatible alternatives include the LM3526M-L/NOPB (lower current threshold variant) and other dual USB power switches from Texas Instruments such as the TPS2065. Third-party alternatives like the MIC2026 or NCP380 may also be considered depending on current limit, fault logic, and package requirements.
