PRODUCT DESCRIPTION
The GLF1511 load switch is a fully integrated 4 A NMOS load switch with IQSmartTM advanced technology. The device is ideal for the mobile computing and data storage markets as a high performance solution for load switch applications.
The GLF1511 provides a constant low onresistance of 13 mΩ at the full input voltage range. 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 GLF1511 consumes ultra-low current at the wide input supply voltage.
The GLF1511 features a reverse current blocking protection. When the GLF1511 is disabled, it prevents reverse current flowing from the output to the input source.
The GLF1511 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.
