Definition
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.
Test Terminal
For test purposes only. Do not connect in the application.
Direct High-Side
Control Input
This terminal allows the enabling and PWM control of the high-side HS1
and HS2 terminals.
Internal Reset Output This terminal is the reset output terminal of the analog die.
Internal Interrupt
Output
This terminal is the interrupt output terminal of the analog die indicating
errors or wake-up events.
Wake-Up Inputs ^{These terminals are the wake-up inputs of the analog chip.}
High-Side Output ^{These output terminals are low R}_DS(ON) ^{high-side switches.}

Output
These terminals are device power supply terminals.
This terminal represents the single-wire bus transmitter and receiver.
These terminals are device power ground connections.
The + 5.0 V voltage regulator output terminal is intended to supply the
embedded microcontroller.
This terminal is the single +5.0 V power supply for the current sense
operational amplifier.
This terminal is the output of the current sense operational amplifier.
These terminals are the current sense operational amplifier inverted
and non-inverted inputs.
This input terminal is for configuration of the watchdog period and
allows the disabling of the watchdog.
This terminal is the output of LIN transceiver.
