LM3525M-H Description

Short technical summary and product information.

The LM3525M-H from NATIONAL is a single-port Universal Serial Bus (USB) standard power switch with integrated over-current protection. It is suitable for host port applications in notebook PCs and handheld devices, supplying power to a single port.

Key electrical specifications include an input voltage range of 2.7V to 5.5V, a minimum continuous load current of 500mA, and a nominal short circuit output current of 1A. The switch resistance is a maximum of 120 mΩ at 5V input. It features a low standby current of 1 µA maximum and an operating current of 100 µA maximum.

The device is designed for smooth turn-on, minimizing inrush current induced voltage drops. It also includes a 1 ms fault flag delay during hot-plug events to prevent erroneous overcurrent reporting. Thermal shutdown protects the device in direct short conditions. The LM3525M-H is compatible with USB 1.1 and USB 2.0 standards.

Packaged in a compact SOIC-8 surface mount package, the LM3525M-H minimizes board space. The operating temperature range is -40°C to 125°C. This component is UL recognized.
