MCU Power Supply
Pins
Port A I /Os
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.
Test Pin
For test purposes only. Do not connect in the application.
Current Limitation ^{This is the input pin for the half-bridge current limitation and the}

force (BEMF).
Internal Reset
This pin is the bidirectional reset pin of the analog die.
Internal Interrupt
Output
This pin is the interrupt output pin of the analog die indicating
errors or wake-up events.
Slave Select
This pin is the SPI slave select pin for the analog chip.
LIN Bus
This pin represents the single-wire bus transmitter and receiver.
Half-Bridge Outputs
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.
Power Supply Pins ^{These pins are device power supply pins.}
Power Ground Pins ^{These pins are device power ground connections.}
High-Side Output
Switchable
V_DD Output
This output pin is a low R_DS(ON) high-side switch.
This pin is a switchable V_DD output for driving resistive loads
requiring a regulated 5.0 V supply; e.g., 3-pin Hall-effect
sensors.
