Announcing the launch of Shindengen's V_DSS 40V/60V motor drive power modules for automotive applications which reduce mounting area by 40% -Contributes to lighter weight and more compact electro-mechanical EPS-

Aug. 24, 2021

Shindengen Electric Manufacturing Co., Ltd. has expanded its lineup with the MG031 Series power modules for drive of 3 phase brushless DC motors such as in automotive electric power steering (EPS).

The 3 "MG031E120004A", "MG031L080006A", and "MG031N110006A" types are MOSFET power modules for motor drive. The 2 "MG031MC148004A" and "MG031MD110006A" types are MOSFET power modules for phase separation relays to isolate the motor from the inverter.

Combining these products allows for creation of motor drive + phase separation relay circuits, which can contribute to lighter weight and more compact electro-mechanical EPS.
In addition to V_DSS=40V products for passenger vehicle applications, we also offer V_DSS=60V products for commercial vehicle applications with more advanced electrification.

We are currently shipping samples of these new products with sales expected to begin in September 2021.

■ Overview

The shift to electrified vehicles is accelerating in automotive markets globally in order to achieve carbon neutrality.

Increasing complexity of the control systems for electrified vehicles has caused concern over increases of ECU components and there is growing demand for lighter weight, downsizing, and better efficiency in order to increase cruising ranges. In response there has also been increased development of electro-mechanical integration in order to achieve more lightweight and compact EPS.

These new products are 6 in 1 MOSFET power modules for drive of EPS 3 phase brushless DC motors and 3 in 1 MOSFET power modules for phase separation relays to isolate motors from inverters.

These products allow for creation of motor drive + phase separation relay circuits from just 2 power modules, achieving a 40% reduction in mounting area compared to similar circuits composed of 9 discrete MOSFET. In addition, combining with use of high heat dissipation modules to downsize heat dissipation systems makes it possible to construct motor drive + phase separation relay circuits in the limited space of electro-mechanical EPS.

Suitable application examples include drive of 3 phase brushless DC motors for automotive oil pumps, water pumps, and other auxiliary systems in addition to EPS

■ Features

Reduction of the number of components improves system safety and reliability
Reducing the number of components through use of 6 in 1 MOSFET modules and 3 in 1 MOSFET modules improves system safety and reliability.

Compact high heat dissipation modules
A large current architecture through exposure of lead frames, and use of Cu clip connections with low electrical resistance and high heat dissipation improves heat dissipation performance by 20% compared to conventional full molded packages and achieves large current capacity in a more compact form.

Cu clip connections provide high reliability
These robust power modules use Cu clip connections instead of Al wire bonding for internal connective structures to improve connection reliability.

Junction temperature (Tch) guaranteed up to 175°C

ROHS compliant, halogen-free, Pb free terminals

Lead terminals are also available in short lead terminals in addition to standard types
