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