Microchip MCP8024 Gate Driver

Microchip MCP8024 Gate Driver

Microchip MCP8024 is a 3-Phase Brushless DC (BLDC) 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 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 0.5A at 12V for driving high-side 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 5V and 12V 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 5x5 QFN and 48-lead 7x7 TQFP.
