STMEC001

Power interface switch for ExpressCardTM

Features

■ Compliant with PC Card

™ standard for

ExpressCard

■ 3-channel power interface switch

■ Built-in under-voltage lockout (UVLO) circuit

■ Ultra-low standby-mode current

■ Additional 5 V or 12 V power supply not

required

■ High reliability ensured with integrated over-

current, thermal and undervoltage protection

circuitries applied to each voltage rail

■ Soft start function for non-rush current

■ Ultra-low standby-mode current for power

saving

■ Ultra-low ON resistance for fast switching

Description

The STMEC001 is an ExpressCard power

interface switch which provides the complete

power management solution required by the

ExpressCard specification.

The STMEC001 consists of 3 internal switches

distributing 3.3 V, 3.3VAUX, and 1.5 V to the

ExpressCard socket without the need of additional

charge pump or external switches.

The STMEC001 ExpressCard power switch is

ideal for notebook computers, desktop computers,

personal digital assistants (PDA), or other

handheld devices implementing the ExpressCard

schematic.
