APPLICATION SCHEMATIC

GLF78131 application schematic

The GLF78131 / GLF78131T is an ultra-efficienct, IQSmartTM LoadSwitch with three independent and identical load switches integrated. Each load switch features an ultra-efficient IQSmartTM technology that supports some of the lowest quiescent current (IQ) and shutdown current (ISD) in the industry. Low IQ and ISD solutions help designers to reduce parasitic leakage current, improve system efficiency, and increase battery lifetime.

The GLF78131 integrated slew rate control can also enhance system reliability by mitigating bus voltage swings during switching events. Where uncontrolled switches can generate high inrush current that result in voltage droop and/or bus reset events, the slew rate control specifically limits inrush current during turn-on to minimize voltage droop.

The GLF78131 Load Switch device supports an industry leading wide input voltage range and helps to improve operating life and system robustness. Furthermore, one device can be used in multiple voltage rail applications which helps to simplify inventory management and reduces operating cost.

The GLF78131 is utilizing a wafer level chip scale package with 12 bumps in a 1.27 mm x 1.67 mm die size and a 0.4 mm bump pitch.

The GLF78131T is ultra-thin. Its thickness is 0.35 mm Typ, 0.4 mm Max.
