28V, Over-Voltage and Over-Current Protection Load Switch with Adjustable Current-Limit Control
  • SKU
    WS4694C
  • Category
    Power Management - Load Switch
  • Application
    Computing, Mobile Devices

The WS4694C is a small, low RON, single channel load switch with controlled slew rate. The device operates over an input voltage range of 2.6V to 5.5V. The device supports current limit from 0.05A to 2A.

The controlled rising time of the device greatly reduces inrush current caused by large bulk load capacitance, thereby reducing or eliminating power supply drop. The WS4694C has a True Reverse-Current Blocking (TRCB) function that obstructs unwanted reverse current from VOUT to VIN during ON and OFF states. The small size and low RON device is designed for space constrained battery powered applications. The wide input voltage range of the switch makes it a versatile solution for many different voltage rails.

The WS4694C are available in a CSP-9L package. Standard products are Pb-free and Halogen-free.

Applications:
– Smart Phones, Tablet PCs
– Storage, DSLRs, and Other Portable Devices

Input voltage range: 2.6V ~ 5.5V

Absolute rating at VOUT: 28V
