Description
The SMA6850MX/MZ 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 SMA6850MX/MZ 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
• Small ventilation fan
• Dishwasher pump

NOTE:
▪
All of the input pins are connected to GND with internal pull-down resistors rated at 100 kΩ, however, an external pull-down
resistor may be required to secure stable condition of the inputs if high impedance conditions are applied to them.
▪
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.
▪
This IPM does not have an overcurrent detection feature. It is recommended to implement the feature externally. When an
overcurrent condition occurs, the application MCU must stop driving the IPM within 2
μs.
▪
Snubber capacitors should be surge suppressor film capacitors with sufficient rating to suppress surge voltavges. To determine
the capacitance for an application, please verify the surge voltage in the actual application.
