Si834x –Quad PLC Output Driver
control systems with integrated safety rated isolation of 2.5 kVrms. The Si834x-IS are non-isolated drivers. The input interface
is based on Silicon Laboratories’ ground breaking CMOS based isolation technology which enables easy interface to low voltage
2.25V MCU’s and the ability to accommodate high data rates of up to 1 Mbps for servo motor control on some product options.
This technology enables high CMTI (25 kV/µs), reduced variation with temperature and age and tighter part-to-part matching.
The outputs provide a continuous 0.7A drive capability for either high side or low side inductive loads, depending on the product
option. These have integrated active clamps to minimize transients and protect the drivers when switching such loads.
Product features include over-current and over-temperature detection and shutdown circuit and diagnostic capability for detecting
open wires when in OFF state and short circuit when in ON state. These diagnostics can be available as grouped for all
four channels or channel specific via an SPI interface on some product options. Status LEDs can be connected to the Si834x
which indicate the true status of the output (ON/OFF or fault condition). Daisy chain capability for a total of 128 channels (32x
Si834x) is also possible with the SPI option. The Si834x offers longer service life and dramatically higher reliability compared
to other solutions.
