Microchip MCP8024

Description

The MCP8024 is a 3-Phase Brushless DC (BLDC) power module. The MCP8024 device integrates three half-bridge drivers to drive external NMOS/NMOStransistor 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.
