Bus
Electrical Common Ground and Heat removal. A good thermal path
will also reduce the die temperature.
Data input here will appear on the BUS terminal. A logic [0] will assert
the bus, a logic [1] will make the bus go to the recessive state.
These Pins control Sleep Mode, Transmit Level, and Speed. They
have weak pulldowns.
Open drain output of the data on BUS. A recessive bus = a logic [1], a
dominant bus = logic [0]. An external pullup is required.
No internal connection to these Pins. Pin 13 can be connected to GND
to allow the use of the 14-terminal or 8-terminal device.
Provides a battery-level logic signal.
Power input. An external diode is needed for reverse battery
protection.
The external bus load resistor connects here to prevent bus pullup in
the event of loss of module ground.
This terminal connects to the bus through external components.
