Ideal Diodes Enhance System Efficiency in Wearable/Wireless Devices
Designed to deliver ultra-efficient power-path protection in compact, battery-powered systems, GLF Integrated Power’s GLF1800 Series of ideal diodes features ultra-low static current (IQ), ultra-low turn-off current (ISD), and a low forward voltage drop (GLF1800: 117 mV and GLF1800T/AT: 73 mV).
These devices significantly reduce power loss and improve overall system efficiency, most notably in always-on or energy-constrained applications such as virtual-reality (VR) headsets, smart glasses, smart meters, wearable medical devices, and IoT sensors.
The GLF1800 ideal diodes feature an SOT23-5L package. Series stablemate GLF1800T/AT ideal diodes offer a WLCSP package for flexibility when employed in more space-constrained system designs. The GLF1800AT EN pin has an internal pull-up resistor connected to VIN.
They support a wide input voltage range of 1.8 to 5.5 V and provide up to 1.0 A or 1.5 A of continuous current.
As a replacement for traditional Schottky diodes, ideal diodes provide a compact footprint while eliminating the need for complex thermal management. The GLF1800 Series integrates multiple protection features, including reverse-current blocking, inrush control, and seamless power-source switching. This combination of features simplifies power-path design while enhancing overall system safety, efficiency and long-term reliability.
Pricing (at DigiKey) is $0.369/1,000 pieces for GLF1800 and $0.399/1,000 pieces for GLF1800T/AT. Samples are in stock with production quantities delivering in 14 to 16 weeks.
