Microchip
Controller, gate driver and communication in one IC
Microchip Technology offers a new series of integrated motor drivers based on the 'dsPIC' digital signal controllers (DSCs) to enable efficient embedded real-time motor control systems in space-constrained applications.
The components combine a 'dsPIC33', a 3-phase MOSFET gate driver and an optional LIN or CAN FD transceiver in one housing. According to the manufacturer Microchip, the advantages of this integration are the reduced number of components in a motor control system, smaller PCB dimensions and reduced complexity. The components are supported by development boards, reference designs, application notes and Microchip's own field-oriented control/FOC software development suite 'motorBench Development Suite V2.45'. The integrated motor drivers can be operated via a single power supply with up to 29 V (operating) and 40 V (transient). An internal 3.3 V low dropout/LDO voltage regulator powers the dsPIC-DSC, eliminating the need for an external LDO to power the device. The motor drivers operate at 70 to 100 MHz.
