Product Description

The GLF72122 are an advanced technology fully integrated IQSmartTM load switch device with Reverse Current Blocking (RCB) technology and the slew rate control of the output voltage.


The GLF72122 offer 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 GLF72122 have 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 GLF72122 can achieve an ISD as low as 56 nA typical at 5.5 V.
