The MCP8024-H/MP is a 3-phase Brushless DC (BLDC) Motor Gate Driver with 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 over-temperature 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 0.5A at 12V for driving high-side and low-side NMOS MOSFET transistors. The driver has shoot-through, overcurrent and short-circuit protection. The MCP8024 buck converter is capable of delivering 750mW of power for powering a companion microcontroller. The buck regulator may be disabled if not used. The on-board 5 and 12V low dropout voltage regulators are capable of delivering 20mA of current.
