Description
The SMA6860MZ inverter power module (IPM) series 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 up to 2.5 A (continuous)
output current. They can withstand voltages of up to 500 V
(MOSFET breakdown voltage).
The SMA6860MZ 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
• Small ventilation fan
• Dishwasher pump
Packages: Power SIP

NOTE:
The external electrolytic capacitors should be placed as close to the IC as possible, in order to avoid malfunctions
from external noise interference. Put a ceramic capacitor in parallel with the electrolytic capacitor if further
reduction of noise susceptibility is necessary.
