Description
The SMA6821MP inverter power module (IPM) device
provides 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 120 VAC input voltage and provide 2 A (continuous)
output current. They can withstand voltages of up to 250 V
(MOSFET breakdown voltage).
The SMA6820MP power package includes an IC with all of
the necessary power elements (six MOSFETs) and pre-driver
ICs (two) needed to configure the main circuit of an inverter.
This enables the main circuit of the inverter to be configured
with fewer external components than traditional designs.
Applications include residential white goods (home
applications) and commercial appliance motor control:
• Air conditioner fan
• Refrigerator compressor
• Dishwasher pump
