Worcester, MA – Allegro MicroSystems, Inc. adds several new devices to their existing Inverter Power Module (IPM) portfolio. The SCM1240M family provides a robust, highly-integrated solution for optimally controlling three-phase motor power inverter systems and variable speed control systems. These devices were designed to conserve energy when driving the motors of both residential and commercial appliances. This new series is offered by Allegro and manufactured and developed by Sanken Electric Co., Ltd. in Japan.

These ICs take 85 to 253 VAC input voltage, and 10 to 30 A (continuous) output current. They can withstand voltages of up to 600 V (IGBT breakdown voltage). The high current SCM1240M series employs a new, small-footprint proprietary DIP package. The IC itself consists of all of the necessary power elements (six IGBTs), pre-drive ICs (three), and freewheeling diodes (six), needed to configure the main circuit of an inverter, as well as a bootstrap circuit (three bootstrap diodes and three boot resistors) as a high-side drive power supply. This enables the main circuit of the inverter to be configured with fewer external components than traditional designs.

Applications include residential white goods (home appliances) and commercial appliance motor control, such as: air conditioner compressor motors, air conditioner fan motors, refrigerator compressor motors and washing machine main motors.
