RT9725A/B

Express Card Power Interface Switch

General Description

Features

^zMeets Express Card Standard (ExpressCard|34 and

The RT9725A/B power distribution switches are designed

to fulfill power management requirements of Express Card

specification. The RT9725A/B supports systems with

single slot ExpressCard|34 and ExpressCard|54 socket.

The device distributes 3.3V, AUX and 1.5V to the Express

Card socket. Each power rail is protected with current

limit circuitry when output load exceeds over-current

threshold or short-circuits occurs. A thermal protection

circuit turns off switches to prevent the device from damage

when power dissipation is increased by continuous heavy

overloads or short-circuits in the switches. The

RT9725A/B is available in WQFN-20L 3x3 package.
