The three half-bridge drivers are capable of delivering a peak output current - Protected against loss of ground of 0.5A at 12V for driving high-side and low-side NMOS - Automatic thermal shutdown MOSFET transistors. The drivers have shoot-through, - LIN Bus dominant time-out overcurrent and short-circuit protection. A Sleep mode Three Half-Bridge Drivers Configured to Drive has been added to achieve a typical key-off quiescent External High-Side NMOS and Low-Side NMOS current of 5 A. MOSFETs: The MCP8025 device integrates a comparator, a buck - Independent input control for high-side voltage regulator, two LDO regulators, power NMOS and low-side NMOS MOSFETs monitoring comparators, an overtemperature sensor, a - Peak output current: 0.5A 12V LIN transceiver, a zero-crossing detector, a neutral simulator and an operational amplifier for motor current - Shoot-through protection monitoring. The phase comparator and multiplexer - Overcurrent and short-circuit protection allow for hardware commutation detection. The neutral Adjustable Output Buck Regulator (750 mW) simulator allows commutation detection without a Fixed Output Linear Regulators: neutral tap in the motor. The buck converter is capable - 5V 30 mA of delivering 750mW of power for powering a - 12V 30 mA companion microcontroller. The buck regulator may be Operational Amplifiers: disabled if not used. The on-board 5V and 12V - one in MCP8025 low-dropout voltage regulators are capable of delivering 30 mA of current. - three in MCP8026 The MCP8026 replaces the LIN transceiver, neutral Overcurrent Comparator with DAC Reference simulator and zero-crossing detector in MCP8025 with Phase Comparator with Multiplexer (MCP8025) two level shifters and two additional op amps.
