MIC94043YFL-TR

MIC94043YFL-TR Description

The MIC94043YFL-TR from Microchip Technology is a high-side P-channel power distribution switch designed for general-purpose load switching applications. This surface-mount 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 integration. Packaged in a 4-pin MLF (Micro Lead Frame) and available in Tape & Reel (TR), it is optimized for automated assembly.

MIC94043YFL-TR Features

• High-Side Configuration: Enables efficient power management in low-voltage circuits.
• Slew Rate Control: Reduces inrush current and EMI, enhancing system reliability.
• Integrated Load Discharge: Safely discharges capacitive loads when switched off.
• Low Rds(on) (28mOhm): Improves thermal performance and power efficiency.
• Wide Voltage Range (1.7V–5.5V): Compatible with battery-powered and portable devices.
