LM3543 Triple Port USB Power Distribution Switch and Over-Current Protection

Check for Samples: LM3543

FEATURES

DESCRIPTION

The LM3543 is a triple high-side power switch that is

an excellent choice for use in Root, Self-Powered and

Bus-Powered USB (Universal Serial Bus) Hubs.

Independent port enables, flag signals to alert USB

controllers of error conditions, controlled start-up in

hot-plug events, and short circuit protection all satisfy

USB requirements.

•

Compatible with USB1.1 and USB 2.0

90mΩ (typ.) High-Side MOSFET Switch

500mA Continuous Current per Port

7 ms Fault Flag Delay Filters Hot-Plug Events

Industry Standard Pin Order

•

Short Circuit Protection with Power-Saving

Current Foldback

The LM3543 accepts input voltages between 2.7V

and 5.5V. The Enable logic inputs, available in active-

high and active-low versions, can be powered off any

voltage in the 2.7V to 5.5V range. The LM3543 limits

the continuous current through a single port to 1.25A

(max.) when it is shorted to ground.

•

Thermal Shutdown Protection

Undervoltage Lockout

Recognized by UL and Nemko

Input Voltage Range: 2.7V to 5.5V

5 µA Maximum Standby Supply Current

16-Pin SOIC Package

The low on-state resistance of the LM3543 switches

ensures the LM3543 will satisfy USB voltage drop

requirements, even when current through a switch

reaches 500 mA. Thus, High-Powered USB

Functions, Low-Powered USB Functions, and Bus-

Powered USB Hubs can all be powered off a Root or

Self-Powered USB Hub containing the LM3543.

Ambient Temperature Range: −40°C to 85°C

APPLICATIONS

•

USB Root, Self-Powered, and Bus-Powered

Hubs

Added features of the LM3543 include current

foldback to reduce power consumption in current

overload conditions, thermal shutdown to prevent

device failure caused by high-current overheating,

and undervoltage lockout to keep switches from

operating if the input voltage is below acceptable

levels.

•

USB Devices such as Monitors and Printers

General Purpose High Side Switch
