MIC94042YFL-TR

MIC94042YFL-TR Description

The MIC94042YFL-TR from Microchip Technology is a high-side power switch designed for general-purpose load switching applications. This P-channel MOSFET-based IC integrates a 1:1 input-to-output ratio and operates within a 1.7V to 5.5V load voltage range, making it ideal for low-voltage systems. With a 3A maximum output current and an exceptionally low 28mOhm typical Rds(on), it minimizes power loss and improves efficiency. The device requires no external supply voltage (Vcc/Vdd), simplifying design and reducing BOM costs. Packaged in a 4-pin MLF (Tape & Reel), it is optimized for surface-mount assembly and complies with ROHS3 and REACH environmental standards.
