Functional pin description
CAN bus receive data output pin
CAN bus receive data input pin
5.0 V pin is a 2% low drop voltage regulator for to the microcontroller
supply.
This is the device reset output pin whose main function is to reset the
MCU.
This output is asserted LOW when an enabled interrupt condition
occurs.
These device ground pins are internally connected to the package lead
frame to provide a 33889-to-PCB thermal path.
Output drive source for the V2 regulator connected to the external series
pass transistor.
Supply input pin.
Output of the internal high-side switch.
Inputs from external switches or from logic circuitry.
5.0 V pin is a low drop voltage regulator dedicated to the peripherals
supply.
Pin for connection of the bus termination resistor to CANH.
Pin for connection of the bus termination resistor to CANL.
CAN high output pin.
CAN low output pin.
Clock input pin for the Serial Peripheral Interface (SPI).
