LND3526H/L-/CB

DUAL USB POWER CONTROL SWITCH

GENERAL DESCRIPTION

FEATURES

The LND3526, is a dual high side power control switch,

with independent enable and flag functions optimized for

self powered and bus- powered universal serial bus

(USB) applications.

•

USB specification compliant

2.7 to 5.5V operating range

2 independent switches

140 mΩ maximum on-resistance

The

LND3526

satisfies

the

following

USB

Active-high or active-low ENABLE

versions

requirements: Each switch channel supplies up to

500mA with internal circuitry limiting the fault current to

750mA. The switch’s 140mΩ on- resistance meets

USB voltage drop requirements. A flag output is

available to indicate fault conditions to the local USB

controller.

•

Independent open drain fault flag pins

500mA continuous load

current per switch

•

Thermal shutdown

Reverse Blocking

Additional features include: UVLO to ensure that the

device remains off until there is a valid input voltage

present, thermal shutdown to prevent switch failure from

high current loads and 3.3V and 5V logic compatible

enable inputs. The LND3526H/L-CB provides additional

circuit breaker functionality if desired.

Soft Start

Fault flag with deglitch filter

Drop in replacement for

industry standard footprints

The LND3526 is available in active-high and active-

low versions in 8-pin die and SOIC packages.

APPLICATIONS

OPERATING WAVEFORMS
