Description  
The SLA6860M 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 SLA6860M series 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.  
Packages: Power SIP  
Not to scale  
Applications include residential white goods (home  
applications) and commercial appliance motor control:  
• Air conditioner fan  
• Small ventilation fan  
• 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 (tblank) 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.
