Description
The SCM124/6xM inverter power module (IPM) devices
provide robust, highly-integrated solutions for optimally
controlling 3-phase motor power inverter systems and
variable speed control systems used in energy-conserving
designs to drive motors of residential and commercial
appliances. These ICs take 85 to 253 VAC input voltage,
and provide 5 to 30 A (continuous) output current. They can
withstand voltages of up to 600 V (IGBT breakdown
voltage).
Ÿ Fault ( FO indicator) signal output at protection activation:
UVLO (low side only), OCP, STP, and TSD
Ÿ Proprietary power DIP package

[PinTrimmed]
The high current SCM124/6xM IPMs employ 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.
