The LS24062RQ23 is an advanced 28V 6A rated bidirectional load switch which provides overload, short circuit, input voltage surge, excessive inrush current and over-temperature protections to power the system. The built-in 24mΩ ultra low RDS(ON) power switch helps reducing power loss during normal operation. The device features two input/output ports, VBUS1 and VBUS2, which are rated at 30V Absolute Maximum. Each port has independent enable, external current limit setting and discharge control pins. The integrated two N-channel power switch M1 and M2 in-series configuration blocks any leakage between VBUS1 and VBUS2 two ports when the device is disabled. The LS24062RQ23 is available in low profile 16 leads QFN 2.5mm x 3.2mm package.
