This terminal is a special-function, bidirectional I/O port terminal that
can is shared with other functional modules in the MCU.
These terminals are the reference voltage terminals for the analog-
to-digital converter (ADC).
These terminals are the power supply terminals for the analog-to-
digital converter.
These terminals are the ground and power supply terminals,
respectively. The MCU operates from a single power supply.
These terminals are special-function, bidirectional I/O port terminals
that are shared with other functional modules in the MCU.
For test purposes only. Do not connect in the application.
This is the input terminal for the half-bridge current limitation PWM
frequency.
This terminal gives the user information about back electromagnetic
force (BEMF).
This terminal is the bidirectional reset terminal of the analog die.
This terminal is the interrupt output terminal of the analog die
indicating errors or wake-up events.
This terminal is the SPI slave select terminal for the analog chip.
This terminal represents the single-wire bus transmitter and receiver.
This device includes power MOSFETs configured as four half-bridge
driver outputs. These outputs may be configured for step motor
drivers, DC motor drivers, or as high-side and low-side switches.
These terminals are device power supply terminals.
These terminals are device power ground connections.
This terminal is a switchable V
requiring a regulated 5.0 V supply; e.g., 3-terminal Hall-effect
sensors.
The + 5.0 V voltage regulator output terminal is intended to supply
the embedded microcontroller.
Ground terminal for the connection of all non-power ground
connections (microcontroller and sensors).
This terminal is the output of LIN transceiver.
The exposed pad terminal on the bottom side of the package
conducts heat from the chip to the PCB board.
