SCM1104MF
High Voltage 3-Phase Motor Driver
Features and Benefits
Description
▪ Each half-bridge circuit consists of a pre-driver circuit that
is completely independent from the others
▪ Protection against simultaneous high- and low-side turning on
▪ Bootstrap diodes with series resistors for suppressing
inrush current are incorporated
TheSCM1104MFinverterpowermodule(IPM)deviceprovides
a robust, highly-integrated solution 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 8A(continuous) output
current. They can withstand voltages of up to 600 V (IGBT
breakdown voltage).
▪ CMOS compatible input (3.3 to 5 V)
▪ Designed to minimize simultaneous current through both
high- and low-side IGBTs by optimizing gate drive resistors
▪ Integrated Fast Recovery Diode (FRD) as freewheeling
diode for each IGBT
▪ UVLO protection with auto restart
▪ Overcurrent protection with off-time period adjustable by
an external capacitor
▪ Fault (FO indicator) signal output at protection activation:
UVLO (low side only), OCP, and STP
▪ Proprietary power DIP package
The SCM1100M 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.
