GLF launches GLF1800 ideal diodes for battery-powered devices

GLF Integrated Power introduced its GLF1800 Series ideal diodes on July 23, 2026, aiming to cut power loss and heat in compact, battery-powered systems. The new parts target wearables, smart meters and IoT sensors with low forward voltage drop, low quiescent current and multiple protection features.

Why it matters: - The GLF1800 Series is aimed at devices where battery life, heat and board space are constant constraints. - Replacing Schottky diodes with a MOSFET-based ideal diode architecture can reduce forward voltage drop and improve power-path efficiency. - The series is positioned for always-on electronics, where small power losses can add up quickly over time.

What happened: - GLF Integrated Power introduced the GLF1800 Series of ideal diodes on July 23, 2026. - The launch targets compact, battery-powered systems used in VR headsets, smart glasses, smart meters, wearable medical devices and IoT sensors. - GLF says the series is designed to deliver ultra-efficient power-path protection in low-voltage electronics.

The details: - The GLF1800 Series features ultra-low static current and ultra-low turn-off current. - The GLF1800 has a forward voltage drop of 117mV. - The GLF1800T/AT has a forward voltage drop of 73mV. - The GLF1800 ships in an SOT23-5L package. - The GLF1800T/AT ships in a WLCSP package for tighter designs. - The GLF1800AT EN pin includes an internal pull-up resistor connected to VIN. - The devices support input voltages from 1.8V to 5.5V. - The series supports up to 1.0A or 1.5A of continuous current. - The parts include reverse-current blocking, inrush control and seamless power-source switching. - GLF says the protection features simplify power-path design while improving system safety, efficiency and long-term reliability. - Pricing is listed at $0.369 for GLF1800 in 1,000-piece quantities through DigiKey. - Pricing is listed at $0.399 for GLF1800T/AT in 1,000-piece quantities through DigiKey. - Samples are in stock in Santa Clara. - Production quantities are expected in 14 to 16 weeks. - GLF provides requests for samples at info@glfipower.com and lists www.glfipower.com for more information.

Between the lines: - The product line gives designers a drop-in alternative to Schottky diodes that can also shrink thermal management needs. - The package choices suggest GLF is targeting both standard layouts and the tightest space-constrained designs. - Eileen Ni Sun, GLF's president and founder, said ideal diodes have become key components for improving power-path reliability and extending battery life in popular electronics.

What's next: - GLF says samples are already available, with volume production following in 14 to 16 weeks. - Designers can request samples or contact a GLF sales representative for deployment planning. - GLF will likely push the series into wearables and other low-power platforms where efficiency gains are easier to commercialize.

The bottom line: - The GLF1800 Series is a small-parts launch with a clear goal: lower loss, less heat and better battery performance in space- and power-limited devices.
