USB POWER CONTROL SWITCHES
A2525EM
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

active high; the A2535EL/EM are active low.
All devices are ideally suited for USB applications. Each switch

RNote that the A2525EM (DIP) and the
OA2525EL (SOIC) are electrically identical and
Tshare a common terminal number assignment.

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.
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.

Applications
* Fault conditions that produce excessive
junction temperature will activate device
thermal shutdown circuitry. These conditions
can be tolerated but should be avoided.

D1695

This part is a darlington connection NPN silicon epitaxial transistor. The 2SD1695 is a Darlington connection transistor and incorporates a dumper diode between the collector and emitter and a constant voltage diode and protection elements between the collector and base. This transistor is ideal for drives in solenoid and actuators.
