Figure 31. RS-485 Half-Duplex Application
Typical Application Circuit
Figure 31 shows the MAX3109 being used in a half-
duplex RS-485 application. The microcontroller, the
RS-485 transceiver, and the MAX3109 are powered by a
single 3.3V supply. SPI is used as the controller’s com-
munication interface. The microcontroller provides an
external clock source to clock the UART.
The MAX14840 receiver is always enabled, so echoing
occurs. Enable auto echo suppression in the MAX3109
by setting the MODE2[7]: EchoSuprs bit high.
Set the MODE1[4]: TranscvCtrl bit high to enable auto
transceiver direction control in order to automatically
control the DE input of the transceiver.
