SLA6845MZ description the SLA6845MZ 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 3 a (continuous) output current. they can withstand voltages of up to 600 v (igbt breakdown voltage). the sla6840m power package includes an ic with all of the necessary power elements (six igbts), pre-driver ics (two), and freewheeling 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 features and benefits ? built-in pre-drive ic ? igbt power element ? cmos compatible input (3.3 to 5 v) ? high-side gate driver using bootstrap circuit or floating power supply ? integrated fast recovery diode (frd) as freewheeling diode for each igbt ? built-in protection circuit for controlling power supply voltage drop ? built-in overtemperature detection circuit (td) ? 3-shunt configuration ? output of fault signal during operation of protection circuit ? output current 3 a ? small sip (sla 24-pin) high voltage 3-phase motor driver functional block diagram figure 1. driver block diagram. leadform 2178 package: power sip high side level shift driver low side driver uvlo uvlo uvlo uvlo input logic input logic uvlo overtemperature detection 7.5 v reg. vcc1 vb 1 vb 2 vb3 vbb 1 vbb 2 u v w1 w2 ls2 ls3 ls1 fo com2 lin3 lin2 lin1 vreg vcc2 com1 hin3 hin2 hin1 leadform 2171 leadform 2175 not to scale SLA6845MZ-ds
