3-phase brushless DC power module from Microchip
The MCP8024 from Microchip is a 3-phase brushless DC (BLDC) power module. The MCP8024 device integrates three half-bridge drivers to drive external NMOS/NMOS transistor pairs configured to drive a 3-phase BLDC motor, a comparator, a voltage regulator to provide bias to a companion microcontroller, power monitoring comparators, an overtemperature sensor, two level translators, and three operational amplifiers for motor current monitoring. The MCP8024 has three half-bridge drivers capable of delivering a peak output current of 0.5 A at 12 V for driving high- and low-side NMOS MOSFET transistors. The drivers have shoot-through, overcurrent, and short-circuit protection. The MCP8024 buck converter is capable of delivering 750 mW of power for powering a companion microcontroller. The buck regulator may be disabled if not used. The on-board 5 V and 12 V low-dropout voltage regulators are capable of delivering 20 mA of current. The MCP8024 operation is specified over a temperature range of -40°C to +150°C. Package options include the 40-lead 5 x 5 QFN and 48-lead 7 x 7 TQFP.
