FUNCTIONAL BLOCK DIAGRAM
The GLF1501 load Switch is a fully integrated 3 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 GLF1501 has a constant low on-resistance of 52 mΩ at room temperature. 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 GLF1501 draws only 6 nA typical at 3.6 V input supply voltage.
The GLF1501 features a reverse current blocking protection. When the GLF1501 is disabled, it prevents reverse current flowing from the output to the input source.
