GLF launches GLF1800 ideal diodes to cut power loss in battery devices

GLF Integrated Power introduced its GLF1800 Series of ideal diodes on July 23, 2026, targeting compact battery-powered products that need lower heat and better power-path efficiency. The new parts replace Schottky diodes with a MOSFET-based design and are aimed at wearables, smart glasses, meters and IoT sensors.

Why it matters: - The GLF1800 Series is aimed at devices where battery life, heat and board space are constant constraints. - The parts replace Schottky diodes with a MOSFET-based architecture to reduce forward voltage drop and power loss. - Lower loss and lower heat can improve reliability in always-on consumer, industrial and medical devices.

What happened: - GLF Integrated Power introduced the GLF1800 Series of ideal diodes on July 23, 2026. - The launch covers GLF1800, GLF1800T and GLF1800AT parts. - The series is designed for compact, battery-powered systems. - Target applications include VR headsets, smart glasses, smart meters, wearable medical devices and IoT sensors.

The details: - The GLF1800 features ultra-low static current and ultra-low turn-off current. - The GLF1800 has a low forward voltage drop of 117 mV. - The GLF1800T and GLF1800AT have a low forward voltage drop of 73 mV. - The GLF1800 uses an SOT23-5L package. - The GLF1800T and GLF1800AT use a WLCSP package for tighter layouts. - The GLF1800AT EN pin has an internal pull-up resistor connected to VIN. - The series supports an input voltage range of 1.8 V to 5.5 V. - The parts provide up to 1.0 A or 1.5 A of continuous current. - The series includes reverse-current blocking, inrush control and seamless power-source switching. - GLF positions the parts as a replacement for traditional Schottky diodes without the need for complex thermal management. - GLF said the series simplifies power-path design while improving system safety, efficiency and long-term reliability. - Pricing through DigiKey is $0.369 per unit for GLF1800 in 1,000-piece quantities. - Pricing through DigiKey is $0.399 per unit for GLF1800T/AT in 1,000-piece quantities. - Samples are in stock in Santa Clara. - Production quantities carry a 14- to 16-week lead time. - GLF said interested customers can email info@glfipower.com or visit the company's website.

Between the lines: - The launch fits GLF’s core focus on ultra-efficient power-control ICs for small electronics. - The package options suggest GLF is trying to serve both general compact designs and more space-constrained layouts. - The emphasis on always-on devices points to markets where even small efficiency gains can translate into longer battery life.

What's next: - GLF is taking samples now and expects production shipments in 14 to 16 weeks. - Customers can request samples or contact a GLF sales representative for design support. - The company is likely betting that lower-loss power-path parts will gain traction in wearables and other low-voltage devices.

The bottom line: - GLF is using a low-loss ideal-diode design to target a basic but high-value problem: reducing wasted power in battery-powered electronics.
