The three half-bridge - Automatic thermal shutdown drivers are capable of delivering a peak output current - LIN bus dominant time-out of 0.5A at 12V for driving high-side and low-side NMOS MOSFET transistors. The drivers have shoot-through, Three Half-Bridge Drivers Configured to Drive overcurrent and short-circuit protection. A Sleep mode External High-Side NMOS and Low-Side NMOS has been added to achieve a typical key-off quiescent MOSFETs: current of 5 A. - Independent input control for high-side NMOS and low-side NMOS MOSFETs The MCP8025A device integrates a comparator, a buck voltage regulator, two LDO regulators, power monitoring - Peak output current: 0.5A at 12V comparators, an overtemperature sensor, a LIN trans- - Shoot-through protection ceiver, a zero-crossing detector, a neutral simulator and - Overcurrent and short-circuit protection an operational amplifier for motor current monitoring. The Adjustable Output Buck Regulator (750 mW) phase comparator and multiplexer allow for hardware Fixed Output Linear Regulators: commutation detection. The neutral simulator allows - 5V at 30 mA commutation detection without a neutral tap in the motor. - 12V at 30 mA The buck converter is capable of delivering 750 mW of power for powering a companion microcontroller. The Operational Amplifiers: buck regulator may be disabled if not used. The on-board - One in MCP8025A 5V and 12V Low-Dropout (LDO) voltage regulators are - Three in MCP8026 capable of delivering 30 mA of current. Overcurrent Comparator with DAC Reference The MCP8026 device replaces the LIN transceiver, Phase Comparator with Multiplexer (MCP8025A) neutral simulator and zero-crossing detector in Neutral Simulator (MCP8025A) MCP8025A with two level shifters, and two additional Level Translators (MCP8026) op amps.
