USB DUAL POWER CONTROL SWITCHES  
The A2526EL/M and A2536EL/M are integrated high-side dual  
power switches, optimized for self-powered and bus-powered Univer-  
sal Serial Bus (USB) applications. Few external components are  
A2526EM  
necessary to satisfy USB requirements. The A2526EL/EM ENABLE  
inputs are active high; the A2536EL/EM are active low.

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.

Note that the A2526EM (DIP) and the  
A2526EL (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.
