Update Alert Share

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.
