The MIC94161YCS-TR is a high-side load switch designed for power management in a compact 1.5mm x 1.5mm WLCSP package. It integrates an N-Channel MOSFET with a low 14.5mΩ on-resistance, supporting up to 3A of continuous current across a wide 1.7V to 5.5V input voltage range. Key protective features include reverse current blocking when disabled and overvoltage protection that safeguards the load if the input exceeds 4.55V. This model provides a controlled soft-start turn-on time of 2.7ms to limit in-rush current, making it ideal for battery-powered applications like solid-state drives, smartphones, and portable instruments.
