2-Wire Bus System
The 2-wire bus system supports operation as a slave-
only device in a single or multislave, and single or multi-
master system. Slave devices can share the bus by
uniquely setting the 7-bit slave address. The 2-wire
interface consists of a serial data line (SDA) and serial
clock line (SCL). SDA and SCL provide bidirectional
communication between the MAX17040/MAX17041
slave device and a master device at speeds up to
400kHz. The MAX17040/MAX17041s’ SDA pin operates
Maxim Integrated
bidirectionally; that is, when the MAX17040/MAX17041
receive data, SDA operates as an input, and when the
MAX17040/MAX17041 return data, SDA operates as an
open-drain output, with the host system providing a
resistive pullup. The MAX17040/MAX17041 always
operate as a slave device, receiving and transmitting
data under the control of a master device. The master
initiates all transactions on the bus and generates the
SCL signal, as well as the START and STOP bits, which
begin and end each transaction.
