LM3526

Dual Port USB Power Switch and Over-Current

Protection

General Description

Features

n 1 ms fault flag delay filters Hot-Plug events

The LM3526 provides Universal Serial Bus standard power

switch and over-current protection for all host port applica-

tions. The dual port device is ideal for Notebook and desktop

PC’s that supply power to more than one port.

n Smooth turn-on eliminates in-rush induced voltage drop

n UL recognized component: REF 205202

n 1A nominal short circuit output current protects PC

power supplies

n Thermal shutdown protects device in direct short

condition

A 1 ms delay on the fault flag output prevents erroneous

overcurrent reporting caused by in-rush currents during

hot-plug events.

The dual stage thermal protection circuit in the LM3526 pro-

vides individual protection to each switch and the entire de-

vice. In a short-circuit/over-current event, the switch dissipat-

ing excessive heat is turned off, allowing the second switch

to continue to function uninterrupted.

n 500mA minimum continuous load current

n Small SO-8 package minimizes board space

n 2.7V to 5.5V input voltage range

n 140 mΩ Max. switch resistance

n 1 µA Max. standby current

The LM3526 accepts an input voltage between 2.7V and

5.5V allowing use as a device-based in-rush current limiter

for 3.3V USB peripherals, as well as Root and Self-Powered

Hubs at 5.5V. The Enable inputs accept both 3.3V and 5.0V

logic thresholds.

n 200 µA Max. operating current

n Under-voltage lockout (UVLO)

Applications

n Universal Serial Bus (USB) Root Hubs including

Desktop and Notebook PC

The small size, low R_ON, and 1 ms fault flag delay make the

LM3526 a good choice for root hubs as well as per-port

power control in embedded and stand-alone hubs.

n USB Monitor Hubs

n Other Self-Powered USB Hub Devices

n High Power USB Devices Requiring In-rush Limiting

n General Purpose High Side Switch Applications
