PRODUCT DESCRIPTION
The GLF1220H and GLF1221H are an ultra-efficiency, 1 A rated, integrated load switch with the slew rate control as well as a true reverse current blocking function. The best-in-class efficiency makes it an ideal choice for use in IoT, mobile, and wearable electronics.
The GLF1220H and GLF1221H feature an ultra- efficient IQSmartTM technology that supports 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 GLF1220H and GLF1221H offer and industry leading true reverse current blocking (TRCB) function in on and off states. The integrated slew rate control can enhance system reliability by mitigating bus voltage swings during switching events. Where uncontrolled switches can generate high inrush currents that result in voltage droop and/or bus reset events, the GLF1220H and GLF1221H slew rate control specifically limits inrush current during turn-on to minimize voltage droop.
