Description
The SLA6805MPinverter 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 85 to 253 VAC input voltage, and 3 A (continuous) output
current. They can withstand voltages of up to 600 V (IGBT
breakdown voltage).
The SMA6800MPpower package includes an IC with all of the
necessary power elements (six IGBTs), pre-driver ICs (two),
and flyback diodes (six), 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

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.
To use the OCP circuit, an external shunt resistor, RS, is needed. The RS value can be obtained from the formula:
RS(Ω) = 0.5 V / Overcurrent Detection Set Current (A) .
A blanking timer is built-in to mask the noise generated on RS at turn-on.
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.
