Main features

REF-MHA50WIMI111T reference design kits are intended for evaluating the IMI111T series of iMOTION™ IPMs.

The main features [1] of IMI111T series are:

• Motion control engine (MCE) as ready-to-use controller solution for variable speed drives

• Field oriented control (FOC) for permanent magnet synchronous motor (PMSM)

• Space vector pulse width modulation (SVPWM) with sinusoidal commutation and integrated protection features

• Single-shunt current sensing through direct interface

• Sensor-less operation

• Integrated analog comparators for overcurrent protection

• Overvoltage and undervoltage protection

• Rotor lock protection

• Built-in temperature sensor (Overtemperature protection)

• Undervoltage lockout

• Integrated minimum deadtime

• Shoot-through prevention

• Two different power IGBT options: 2 A/600 V, 4 A/600 V

• Two different supply voltage options for controller: 3.3 V, 5 V

• 15 V supply voltage for gate driver

• Integrated bootstrap diode structure

• Flexible host interface options for speed commands: UART, SPI, PWM, or analog signal

• Class B pre-certification for MCE 2.0 firmware

• Isolation 1500 VRMS 1 min

• Very compact DSO22 package

The main characteristics of the reference board are:

• Typical fan driver 5-pin connector including VDC/GND/VCC/VSP/FG

• Single-shunt current sensing configuration

• Voltage divider for DC-link voltage sensing

• PCB dimensions: 52.0 mm x 52.0 mm, single layer, 1 oz copper

• RoHS compliant
