GLF72520 Application Schematic


The GLF72520 Load Switch is a fully integrated 4 A NMOS load switch with IQSmartTM advanced technology. The device is targeted for the mobile computing and data storage markets as a high performance, low cost solution for load switch applications.

The GLF72520 has a constant low on-resistance of 10 mΩ at room temperature and a supply current consumption of less than 100 nA at lower input voltages. The fixed rise time helps prevent undesirable inrush current when turned on and the internal EN pin pulldown resistor ensures the device remains in the shutdown mode when disabled. In shutdown mode the GLF72520 draws only 6.5 nA typical at 3.6 V input supply voltage

The GLF72520 is available in a wafer level chip scale package (WLCSP) measuring 0.97 mm x 1.47 mm x 0.55 mm with a 0.5 mm pitch. This allows the user to save board space and increase cost savings.
