Device Overview

Summary

The MCP8025A 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 5V and 12V low dropout voltage regulators are capable of delivering 30 mA of current.

The MCP8025A supports a broad temperature range of -40°C to +150°C. Package options include the 40-lead 5x5 QFN and 48-lead 7x7 TQFP.
