Rohm offerds five-model lineup of low(ON) resistance 100V dual MOSFETs

Rohm has developed dual MOSFETs that integrate two 100V chips in a single package – ideal for fan motor drive applied in communication base stations and industrial equipment. Five models have been added as part of the HP8KEx/HT8KEx (Nch+Nch) and HP8MEx (Nch+Pch) series.

Unlike multiple individual drive MOSFETs normally applied in fan motors, dual MOSFETs that integrate two chips in one package are increasingly being adopted to save space.

Rohm’s two new series combine Nch and Pch MOSFET chips using the latest processes. Both series achieve the industry’s lowest RDS(ON) by adopting new backside heat dissipation packages with excellent heat dissipation characteristics. As a result, RDS(ON) is claimed to reduce by up to 56 per cent compared with standard dual MOSFETs (19.6mOhm for the HSOP8 and 57.0mOhm for the HSMT8 Nch+Nch), contributing to significantly lower set power consumption. At the same time, combining two chips in a single package provides greater space savings by reducing area. For example, replacing two single-chip TO-252 MOSFETs with one HSOP8 decreases footprint by 77 per cent.

Rohm will continue to expand its dual MOSFET lineup to withstand voltages ideal for industrial equipment while also developing low-noise variants. This is expected to contribute to solving social issues such as environmental protection by saving space and reducing power consumption in various applications.

Combining these products with Rohm’s market-proven pre-driver ICs for single-/3-phase brushless motors makes it possible to consider even smaller motors featuring lower consumption and quieter drive. By providing total support for peripheral circuit design that marries the dual-MOSFET series with pre-driver ICs, ROHM can offer the best motor drive solutions for customer needs.
