The SY20877B is a 5.3mΩ, single-channel load switch with an N-channel MOSFET that can operate over an input voltage range of 0.285V to 5.5V and can support a maximum continuous current of 10A. The wide input voltage range and high current capability enable the device to be used across multiple designs and end equipment. 5.3mΩ ON resistance minimizes the voltage drop across the load switch and associated power loss.

The controlled rise time for the device greatly reduces inrush current caused by large bulk load capacitances, thereby reducing or eliminating power supply droop.

The SY20877B has an optional 50Ω discharge resistor for quick discharging of the output when the switch is disabled, in order to avoid any unknown state caused by a floating power supply to the downstream load.

The SY20877B is available in a small, spacesaving QFN1.52 package. The device is designed for operation over the
