General Description
The MIC94050 and MIC94051 are 4-terminal silicon gate P-channel MOSFETs that provide low on-resistance in a very small package.
Designed for high-side switch applications where space is critical, the MIC94050/1 exhibits an on-resistance of typically 0.125Ω at 4.5V gate-to-source voltage. The MIC94050/1 also operates with only 1.8V gate-to-source voltage.

FEATUREs
• 0.125Ω typical on-resistance at 4.5V gate-to-source voltage
• Operates with 1.8V gate-to-source voltage
• Separate substrate connection allows reverse-blocking

APPLICATIONs
• Distributed power management
• PCMCIA card power management
• USB ports
• Battery-powered computers, peripherals
• Handheld bar-code scanners
• Portable communications equipment
• Reverse blocking battery management
