Motortreiber, für DC-Motoren, TQFP-48

The MCP8025 is a 3-Phase brushless motor gate driver and power module that integrates the following features: key-off Sleep mode, a LIN transceiver, a buck voltage regulator, two LDO regulators, power monitoring comparators, an over-temperature sensor, a zero-crossing detector, a neutral simulator, a comparator, and an operational amplifier for motor current monitoring.
The phase comparator and multiplexer allow for hardware commutation detection. The neutral simulator allows commutation detection without a neutral tap in the motor. The 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 30 mA of current.
