Advanced Battery Charger Solutions for Scalable Power

Advanced Solutions for Scalable Battery Chargers

onsemi delivers cutting-edge battery charger solutions designed for energy infrastructure and industrial applications. Our portfolio spans from compact 65W USB PD chargers to industrial 3kW+ systems.

Overview

onsemi offers a range of tested solutions to design compact and efficient battery charger solutions from 65W to 600W and beyond. USB is used in battery chargers for power levels up to 240W, making use of the extended power range and adjustable voltage supply options, in addition to the programmable power supply options available up to 100W. Combining onsemi’s USB PD controllers with medium voltage MOSFETs and load switches ensures great control of the output voltage and current requested by the device connected to the USB power supply.

From 240W up to 3kW, the combination of innovative totem-pole technology combined with multi-mode PFC control of EliteSiC MOSFETs or GaN HEMTs enables a compact PFC stage with excellent efficiency from low to high load conditions.

Products

Silicon Carbide (SiC) MOSFETs

Our SiC MOSFETs are designed to be fast and rugged and include system benefits from high efficiency to reduced system size and cost. MOSFETs are metal–oxide–semiconductor field-effect transistors with insulated gates. These silicon carbide MOSFETs have a higher blocking voltage and higher thermal conductivity than silicon MOSFETs, despite having similar design elements. SiC power devices also have a lower state resistance and 10 times the breakdown strength of regular silicon. In general, Systems with SiC MOSFETs have better performance and increased efficiency when compared to MOSFETs made with silicon material.

There are many advantages to choosing SiC MOSFETs over silicon MOSFETs, such as higher switching frequencies. High-temperature development is also not a concern when using SiC MOSFET modules because these devices can operate efficiently even in high heat. Additionally, with SiC MOSFETs, you benefit from a more compact product size because all components (inductors, filters, etc.) are smaller.

Silicon Carbide (SiC) Cascode JFETs
Our high-performance SiC cascode JFETs deliver best-in-class switching speed, lower switching losses, and higher efficiency. They provide high switching frequency and deliver ultra-low on-resistance (RDS (on)) starting at just 5mohm, utilizing less than half the die size of any other technology. Available in both standard thru-hole (including Kelvin) and surface mount packages, they offer excellent cost-effectiveness. These devices utilize a unique cascode configuration, integrating a high-performance SiC fast JFET with a cascode-optimized Si-MOSFET. This innovative approach enables standard gate drive (0-12V) for SiC devices. Given their smaller die size and compatibility with existing driver solutions, the SiC cascode JFETs offer optimized system performance and cost structure.
