ISO808ATR

ISO808ATR is a galvanic isolated 8- channel driver featuring a low supply current. Each driver contains 2 independent galvanic isolated voltage domains (VCC and VDD for the process and control logic stages, respectively). The IC is intended for driving any kind of load with one side connected to ground. The control logic stage features an 8bit output status register (where the MCU sets the ON/OFF status of the output channels in the process stage), daisy chaining is allowed. The two stages communicate through the galvanic isolation channel by an ST proprietary protocol. Active channel current limitation (OVL) combined with thermal shutdown (OVT), independent for each channel, protects the device against overload. Applications include programmable logic control, industrial PC peripheral input/output, numerical control machines, drivers for all type of loads (resistive, capacitive, inductive).
