They also go hand in hand with unconventional PCB designs with severe space constraints that limit the use of external components.
In a move designed to address these challenges, Infineon Technologies has expanded its GaN portfolio with the CoolGaN Drive product family.
This family consists of the CoolGaN Drive 650 V G5 single switches, integrating one transistor plus gate driver in PQFN 5x6 and PQFN 6x8 packages, as well as the CoolGaN Drive HB 650 V G5 devices, combining two transistors with integrated high- and low-side gate drivers in a LGA 6x8 package.
The new product family enables improved efficiency, reduced system size, and overall cost savings and is suitable for longer-range e-bikes, portable power tools, and lighter-weight household appliances such as vacuums, fans, and hairdryers.
The CoolGaN Drive family offers a wide range of single switches and half bridges with integrated drivers based on the recently announced CoolGaN Transistors 650 V G5. Depending on the product group, the components feature a bootstrap diode and are characterised by loss-free current measurement, and adjustable switch-on and switch-off dV/dt.
They also provide OCP/OTP/SCP protection functions. As a result, the devices enable higher switching frequencies, leading to smaller and more efficient system solutions with high power density. At the same time, the bill of materials (BoM) is reduced. This not only results in a lower system weight, but also reduces the carbon footprint.
