Pin Number
Pin Name
Definition
1
VCC
5V typical power supply pin. typical supply current is less than 1.5mA
2
REF-IN-L
Input reference for C2 comparator.
3
REF-IN-K
Input reference for C1 comparator.
4
LO
This pin control Sleep Mode, Transmit Level, and Speed. It has a weak pulldown.
5
RXD
Open drain output of the data on BUS. A recessive bus = a logic [1], a dominant bus = logic [0]. An
external pullup is required.
6
TXD
Data input here will appear on the BUS pin. A logic [0] will assert the bus, a logic [1] will make the bus
go to the recessive state.
7, 8
NC
No internal connection to these pins.
9
DIA
Provides a battery-level logic signal.
10
GND
Electrical Common Ground and Heat removal. A good thermal path will also reduce the die
temperature.
11
I1
Power input. An external diode is needed for reverse battery protection.
12
L
The external bus load resistor connects here to prevent bus pullup in the event of loss of module
ground.
13
VS
This pin connects to the bus through external components.
14
REF-OUT
Internal reference voltage generator output pin.
