DescripTion
The
LTC
®
2874
provides a rugged, 4-port IO-Link power and
communications interface to remote devices connected
by cables up to 20m in length.
Output supply voltage and inrush current are ramped
up in a controlled manner using external N-channel
MOSFETs, providing improved robustness compared to
fully integrated solutions.
Wake-up pulse generation, line noise suppression, con-
nection sensing and automatic restart after fault conditions
are supported, along with signaling at 4.8kb/s, 38.4kb/s,
and 230.4kb/s.
Configuration and fault reporting are exchanged using
a SPI-compatible 4-wire interface that operates at clock
rates up to 20MHz.
The LTC2874 implements an IO-Link master PHY. For
IO-Link device designs, see the
LT
®
3669.
