Description:
The MCP8024 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 0.5A 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.
