Description
The SMA6863M 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 230 VAC input voltage, and 2.5 A (continuous) output
current. They can withstand voltages of up to 500 V (MOSFET
breakdown voltage).
The SMA6800M power package includes an IC with all of
the necessary power elements (six MOSFETs), pre-driver ICs
(two), and bootstrap diodes (three), 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

A. SD1, SD2 terminals are used for both input and output.
B. SD1, SD2, and OCL terminals are open-collector output. RC terminal is open-drain output.
C. Blanking Time (t_blank) is used in Overcurrent Limiting (OCL) and Overcurrent Protection (OCP).
If the time exceeds the limit, the signal will be output (open-collector output turns on), and protection
operation will start up.
