GLF72101 Application schematic

The GLF72101 is an advanced technology fully integrated IQSmartTM load switch device with True Reverse Current Blocking (TRCB) technology and the slew rate control of the output voltage.

The GLF72101 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.

The GLF72101 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 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 GLF72101 can achieve an ISD as low as 20 nA typical at 5.5 V.

The GLF72101 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 GLF72101 load switch device is small utilizing a chip scale package with 6 bumps in a 0.77 mm x 0.77 mm x 0.46 mm die size and a 0.4 mm pitch.
