Together with a dsPIC33 digital sign controller (DSC), motor drivers from Microchip pack a three-phase MOSFET gate driver and non-obligatory LIN or CAN FD transceiver. These built-in units cut back the part rely, PCB measurement, and complexity of embedded motor management programs in space-constrained purposes.
Actual-time processing is enabled by the dsPIC33 DSC, which operates between 70 MHz and 100 MHz. It supplies as much as 256 kbytes of ECC flash reminiscence, 12-bit ADCs, and a 32-bit optical/incremental encoder interface. The DSC additionally helps field-oriented management (FOC) and different superior motor management algorithms.
The built-in motor drivers function from a single energy provide as much as 29 V with transient tolerance as much as 40 V. An inner 3.3-V low-dropout voltage regulator powers the dsPIC33 DSC, eliminating the necessity for an exterior LDO. Certified to AEC-Q100 Grade 0 necessities, the units function from -40°C to +150°C.

The dsPIC33-based motor drivers are supported by an ecosystem of software program and {hardware} improvement instruments. These embrace the dsPIC33CK motor management starter package and MCLV-48V-300W improvement board. The motorBench improvement suite is a free GUI-based device for FOC. Additionally obtainable are varied reference designs, together with an automotive cooling fan and drone propeller controller.
