Description

The SLA6868MZ and SLA6870MZ inverter power module

(IPM) ICs provide 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

3 A (continuous) output current. They can withstand voltages

of up to 500 V (MOSFET breakdown voltage).

The SLApower 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.

Applications include residential white goods (home

applications) and commercial appliance motor control:

• Air conditioner fan

• Small ventilation fan

• Dishwasher pump

Features and Benefits

▪ Built-in pre-drive IC

▪ MOSFET power element

▪ Alleviate noise generation by adjusting an internal resistor

▪ 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 (UVLO on VCC)

▪ Overcurrent protection (OCP), overcurrent limiting (OCL),

and thermal shutdown (TSD)

▪ Output of fault signal during operation of protection circuit

▪ Output current 1.5, 2.5, or 3 A

▪ Small SIP (SLA 24-pin)

A. ¯S¯¯¯D¯¯1¯, ¯S¯¯¯D¯¯2¯ terminals are used for both input and output.

B. ¯S¯¯¯D¯¯1¯, ¯S¯¯¯D¯¯2¯, and ¯O¯¯¯C¯¯L¯ terminals are open-collector output. RC terminal is open-drain input.

If the time exceeds the limit, the signal will be output (open-collector output turns on), and protection

operation will start up.
