Description

The SMA6860M 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 SMA6860M 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.

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, or 2.5 A

▪ Small SIP (SMA 24-pin)

Not to scale

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.

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

operation will start up.
