MCP8024 BLDC Motor Driver Evaluation Board

The MCP8024 Evaluation Board is a platform which demonstrates Microchip’s MCP8024 3-Phase Brushless DC (BLDC) Gate Driver in a BLDC motor drive application. The featured device integrates three Half-Bridge Drivers to drive external NMOS/NMOS transistor pairs, a comparator, a voltage regulator, power monitoring comparators, an over-temperature sensor, two level translators and three operational amplifiers into one IC.

The evaluation board allows designers to quickly and easily start assessing the device and includes a start-stop pushbutton and motor speed controlling potentiometer on board. To implement the demonstrated trapezoidal BLDC Motor Controller solution the MCP8024 is used in combination with a companion Digital Signal Controller, Microchip’s dsPIC33FJ32MC204, which is present in Plug-In Module form.
