FUNCTIONAL BLOCK SCHEMATIC
APPLICATION SCHEMATIC
The GLF74130 IQSmartTM is an advanced technology fully integrated power path load switch with the ability to automatically select between two input sources depending on the input voltage level of each source. The power path switch is targeted for the data storage and mobile markets and is therefore available as a chip scale package utilizing 12 bumps in a 1.27 mm x 1.67 mm x 0.55 mm die size to deliver the highest performance lowest cost power path switch solution in the industry.
The GLF74130 has a built-in reverse current blocking protection. When both switches are at the off mode, the GLF74130 prevents the reverse current from a higher output voltage to the input side.
The EN pin can be used along with the SEL pin to control the switches of the GLF74130. By the combination of these two pins, one of input source selection modes is set among the automatic, VIN1, or VIN2 selection.
