The SY28481B load switch is an ultra-low onresistance, compact device with inrush current limit via programmable soft−start. The device provides power good signaling for system status monitoring and downstream load control. With soft-start capabilities to reduce inrush current and low power consumption in a small footprint, the SY28481B is ideal for power management and hot-swap applications.

The SY28481B is available in a compact DFN33-12 package.
