USB POWER CONTROL SWITCHES

The A2525EL/M and A2535EL/M are integrated high-side power

switches, optimized for self-powered and bus-powered Universal Serial

Bus (USB) applications. Few external components are necessary to

satisfy USB requirements. The A2525EL/EM ENABLE inputs are

active high; the A2535EL/EM are active low.

A2525EM

OUT

FLG

GND

All devices are ideally suited for USB applications. Each switch

channel supplies up to 500 mA as required by USB peripheral devices.

In addition, the switch’s low on-resistance permits achieving the USB

voltage-drop requirements. Fault current is limited to typically

750 mA, satisfying the UL 25 VA safety requirements, and a flag

output is available to indicate a fault condition to the local USB

controller. Momentary voltage drops that may occur on the upstream

port when the switch is enabled in bus-powered applications is elimi-

nated by a “soft start” feature.

Dwg. PP-070A

Note that the A2525EM (DIP) and the

A2525EL (SOIC) are electrically identical and

share a common terminal number assignment.

Additional features include thermal shutdown to prevent catastrophic

switch failure from high-current loads, undervoltage lockout to ensure

that the device remains OFF unless there is a valid input voltage

present, and 3.3 V and 5 V logic-compatible enable inputs.

These switches are provided in 8-pin mini-DIP (suffix ‘M’) and

8-lead SOIC (suffix ‘L’) packages.
