IQSmart Load Switches Extend Battery Life in Wearable Applications
GLF Integrated Power, Inc. announces mass market release of the first product in its IQSmart™ line of high-performance load switches
GLF Integrated Power, Inc., an emerging leader in efficient power switch technology, announces mass market release of the first product in its IQSmart™ line of high-performance load switches. The GLF71311 load switch offers these best-in-class features: an off-state leakage current (ISD) of 5 nA, typ., at 3.3 VIN; a logic operating current (IQ) of less than 10 nA, typ., up to 5.5 V; and an on-state resistance (RON) of 34 mOhms, max, at 5.5V and 41mOhms (max) at 3.3V. Add to this a tiny 0.97 by 0.97mm form factor, and designers now have an ultra-efficient alternative for improving power efficiency in their wearables, mobile medical devices and other battery-powered devices that is significantly better than competing load switches – and dramatically better than using discrete devices.
The GLF1311 load switch’s 5 nA off-state leakage is best in class. This is important since a load switch saves power by turning off power-hungry subsystems when not in use. To maximize efficiency, the system must be “really” off, and off-state leakage, or ISD, is a measure of just how off a system is. The lower the ISD, the less power is wasted in the off state. The GLF1311 load switch’s typical off-state leakage is up to 50 times lower than the nearest competitive load switch device. It also has half the on-state resistance and exhibits as much as 700 times lower logic operating current. These features combine to reduce both power dissipation and battery drain compared with other fully integrated load switches.
About GLF Integrated Power
GLF Integrated Power is a fabless semiconductor company based in Santa Clara, California. Founded in 2013, the company is a supplier of breakthrough, ultra-efficient, ultra-small, silicon power control and protection ICs. When the IoT, ultra-portable and wearable revolution was starting, the GLF founding team saw the need for a new generation of more efficient power switch devices. This was when GLF Integrated Power was born. The company has developed new IP that enables cost-effective, efficient and differentiated power management solutions.
