The LQ05041RCS6 is an advanced technology fully integrated high efficiency load switch device with Reverse Current Blocking (RCB) technology and the slew rate control of the output voltage.

The LQ05041RCS6 offers industry leading Reverse Current Blocking (RCB) performance, featuring an ultra-low threshold voltage. It minimizes reverse current flow in the event that the VOUT pin voltage exceeds the VIN voltage.

The LQ05041RCS6 has industry leading efficiency. It features a 14 mΩ RON typical at 5.5 V, reducing power loss during conduction. The device also features 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, The LQ05041RCS6 can achieve an ISD as low as 56 nA typical at 5.5 V.

The LQ05041RCS6 load switch device support 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 LQ05041RCS6 load switch device is in a 0.97 mm x 1.47 mm x 0.55 mm chip scale package with 6 bumps and a 0.5 mm pitch.
