Key Featrues
1 ms Fault Flag Delay Filters Hot-Plug Events – Prevents false overcurrent reporting during hot-plug events, improving reliability and reducing the risk of erroneous shutdowns or disruptions.
Thermal Shutdown Protection – Safeguards the device and connected components by automatically turning off a switch in case of excessive heat, ensuring uninterrupted operation of the second switch and preventing damage.
2.7V to 5.5V Input Voltage Range – Supports a broad range of input voltages, making it suitable for both 3.3V USB peripherals and 5.5V root hubs, increasing its adaptability in diverse applications.
140 mΩ Max. Switch Resistance – Minimizes power loss and improves efficiency, making it ideal for applications requiring low power consumption and high performance, such as embedded and stand-alone hubs.
Applications
Embedded USB Hub Power Control: The LM3526 is perfect for embedded systems requiring per-port power control in USB hubs. Its low RON and small SOIC-8 package make it a compact and efficient solution for managing power in space-constrained embedded applications.
In-Rush Current Limiter for USB Peripherals: The LM3526 is well-suited for use as an in-rush current limiter for 3.3V USB peripherals. Its smooth turn-on feature eliminates in-rush induced voltage drops, ensuring stable power delivery during hot-plug events.
Thermal Protection for USB Root Hubs: The LM3526 provides robust thermal protection for USB root hubs, ensuring uninterrupted operation even during short-circuit or over-current events. Its dual-stage thermal protection circuit safeguards individual switches and the entire device, making it ideal for demanding USB hub applications.
