The SY28481 load switch is an ultra-low on-resistance, 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 capability to reduce inrush current and low power consumption in a small footprint, the SY28481 is ideal for power management and hot-swap applications.
Under voltage lockout, short circuit protection and overternperature shutdown features are provided for reliable operation.
The SY28481 is available in a compact DFN33-12 package.
