Power Solutions

Richardson Electronics introduces Qorvo’s battery management ICs, offering fully-integrated, configurable and single-chip solutions for today’s ultra-compact battery-operated devices that use Li-ion or Li-polymer batteries. Qorvo’s unique system-on-chip (SoC) solutions offer many benefits, including exceptional device performance, reduced cost and design footprint, sophisticated battery protection, and fast time-to-market.

5.4 mΩ, 750V SiC FETs in TOLL Package for High-Power Applications:

A new surface-mount TO-leadless (TOLL) package for the high-performance, 5.4 milliohm (mΩ) 750V SiC FETs is now available. The UJ4SC075005L8S is the first product in a family of 750V SiC FETs released in the TOLL package with on-resistance ranging from 5.4 mΩ to 60 mΩ. These devices are ideal for use in space-constrained applications such as AC/DC power supplies ranging from several 100s of watts to multiple kilowatts, as well as solid-state relays and circuit breakers up to 100A.

In the 600/750V class of power FETs, Qorvo Gen4 SiC FETs offer unmatched performance across the main figures of merit for on-resistance and output capacitance. Additionally, in the TOLL package, at 5.4 mΩ the devices have 4-10x lower on-resistance than competing best-in-class Si MOSFETs, SiC MOSFETs and GaN transistors. The 750V rating of the SiC FETs is also 100-150 volts higher than the alternative technologies, providing a significantly enhanced design margin for managing voltage transients.

The TOLL package is 30% smaller in footprint, and at 2.3 mm it’s half the height of comparable alternative D2PAK surface-mount offerings.
