Microchip has added ten 16-bit controllers in 28- and 44-pin packages for motor control designs.

Also available is a motor control development platform based on the Explorer 16 development board.

Microchip announced five motor control software solutions for:  Power Factor Correction (PFC), sensorless Field Oriented Control (FOC) of a PMSM motor, sensorless FOC of an ACIM motor, sensorless control of a BLDC motor using Back EMF filtering and sensorless BLDC control with Back-EMF Filtering Using a Majority Function.

Package sizes are as small as 6x6mm, and there is up to 128kbyte of flash memory for large proprietary algorithms such as observer motor control models; integration of motor control algorithms with system-level control; communication stacks such as CAN; and graphic libraries for displays.

Two of the devices feature 16-bit digital-to-analogue converters which can be used for motor noise reduction strategies or audio messaging. A user-selectable 10- or 12-bit analogue-to-digital converter is also available on chip.

All of the devices have a three-phase PWM controller, plus two additional PWM outputs on a separate time base.
