SLA6805MP High Voltage 3-Phase Motor Driver www.datasheet4u.com Features and Benefits ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ Built-in pre-drive IC IGBT power element CMOS compatible input (5 V) High-side gate driver using bootstrap circuit or floating power supply Built-in protection circuit for controlling power supply voltage drop Overcurrent protection circuit (OCP) Output of fault signal during operation of protection circuit Output current 3 A Small SIP (SLA 23-pin) Not to scale Description The SLA6805MP 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 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 SMA6800MP power 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 Packages: Power SIP Leadform 2151 Leadform 2152 (IEC) Leadform 2153 Functional Block Diagram High-Side Driver VCC HV LEV EL SHIFT HIN P U LS E U LS E R G ENP ER A TO UV D ETEC T P U LSE FILTER R R S Q VB HO HS COM VCC LIN1 D ELA Y UV D ETEC T LO 1 Low-Side Driver LIN2 D ELA Y LO 2 LIN3 D ELA Y COM BLANK TIMER and HOLD RC OCP LO 3 RS FO (TOTEM POLE) VTRIP Figure 1.

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.
