DC интеллектуальные ключи MIC94069YML TR

Переключатель силовой нагрузки , высокая сторона, активный высокий, 2 выхода, 5.5В, 2А, MLF-8

The MIC94069YML TR is a dual high-side Load Switch designed for operation between 1.7 to 5.5V. The device contains a pair of low on-resistance, 115mR (maximum) P-channel MOSFETs that support over 2A of continuous current. The MIC94069 feature an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an OFF state. An active pull-down on the enable input keeps MIC94069 in a default OFF state until the EN pin is pulled to a high level. The built-in level shift circuitry allows for a logic signal that may be different from the supply voltage to switch the high-side P-channel MOSFET on or off. The MIC94069 provide a slew rate controlled Soft-Start turn-on of 800µs (typical) to prevent in-rush current from glitching supply rails. MIC94069 voltage range makes them suitable for 1-cell Lithium ion and 2- to 3-cell NiMH/NiCad/Alkaline powered systems, as well as all 5V applications.

• 85mR (typical) R ON
• Built-in level shift for control logic; can be operated by 1.5V logic
