Microchip | MIC94045YFL-TR

The MIC94045YFL TR is a high-side load switch designed to operate from 1.7 V to 5.5 V input voltage. Available in surface mount MLF-4 package.

This device provides a slew rate controlled soft-start turn-on of 1 ms (typical) to prevent an in-rush current event from pulling down the input supply voltage. It features an active load discharge circuit which switches in a 200 Ω load when the switch is disabled to automatically discharge a capacitive load.

Features:

• 28 mΩ RDSON
• 3 A continuous operating current
• 1.2 mm x 1.2 mm space saving 4-pin MLF package
• 1.7 V to 5.5 V input voltage range
• Internal level shift for CMOS/TTL control logic
• Ultra low quiescent current
• Micro-power shutdown current
• Soft-Start: 1 ms
• Load discharge circuit: MIC94045
• Ultra fast turn off time
• Junction operating temperature from -40 °C to +125 °C

Applications:

• Solid State Drives (SSD)
• Cellular phones
• Portable Navigation Devices (PND)
• Personal Media Players (PMP)
• Ultra Mobile PCs
• Portable instrumentation
• Other Portable applications
• PDAs
• Industrial and DataComm equipment
