The LQ05021RCS4 is an advanced technology fully integrated load switch device with true reverse current blocking (TRCB) technology and the slew rate control of the output voltage. It offers industry leading true reverse current blocking (TRCB) performance, featuring an ultra-low threshold voltage. It minimizes reverse current flow in the event that the VOUT pin voltage exceeds the VIN voltage.
It has industry leading efficiency. It features a RON as low as 37 mΩ typical at 5.5 V, reducing power loss during conduction. The device also feature ultra-low shutdown current (ISD) to reduce power loss and battery drain in the off state. When EN is pulled low, and the output is grounded, It can achieve an ISD as low as 20 nA typical at 5.5 V.
The LQ05021RCS4 load switch device supports an industry leading wide input voltage range and helps to improve operating life and system robustness. Furthermore, one device can be used in multiple voltage rail applications which helps to simplify inventory management and reduces operating cost.
The LQ05021RCS4 load switch device is small utilizing a chip scale package with 4 bumps in a 0.77 mm x 0.77 mm x 0.46 mm die size and a 0.4 mm pitch.
