GLF Integrated Power, a power switch technology developer, introduces the GLF71301 load switch offering breakthrough on-state resistance (RON: 34 mOhms, typ, at 5.5 V) in an ultra-small (0.77 by 0.77 mm) form factor.
As the latest addition to its IQSmart line of high-performance load switches, the GLF71301 maximizes system efficiency and optimizes battery life. In addition to the low RON, the GLF71301 also boasts best-in-class off-state leakage current (ISD) of 7 nA, typ., at 3.6 VIN as well as low logic operating current (IQ) of less than 1 nA, typ. at 3.6 V. Applications consist of those that require ever-smaller, more efficient load switches, such as wearables, data storage, SSD, mobile devices, low power systems and battery-powered systems.
Based on GLF’s new and advanced technology, the GLF71301 exhibits unmatched RON performance in a load switch of its size. Although in a form factor almost 40% smaller than GLF’s prior-generation GLF71311, it achieves space savings with minimal impact to on-resistance. Compared to competitive devices, the GLF71301 offers between 28% to 53% lower RON. This extremely low on-resistance translates into higher operating efficiency and extended battery life.
The GLF71301 device’s other best-in-class efficiency specs are off-state leakage and logic operation current. The GLF71301 load switch’s 7 nA off-state leakage is up to 20 times lower than competitive load switch devices. To increase efficiency, a load switch saves power by turning off power-hungry subsystems when not in use; so the lower the ISD, the less power is wasted in the off state.
Additionally, the GLF71301 has a logic operating current, or IQ, of just 1 nA. This is over 70 times lower than its closest competitor and several hundred times lower than other devices. The GLF71301 load switch’s ISD and IQ combine to better reduce power dissipation and battery drain than other fully integrated load switches.
