The ISO8200AQ is a galvanic isolated 8-channel driver featuring a very low supply current. It 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 8-bit Output Status Register (where the μC sets the status ON/OFF of the output channels in the Process Stage) and an 8-bit Fault Register (where the OVT faults of each channel are stored). 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 and overtemperature.
Additional embedded functions are: loss of ground protection, VCC and VDD UVLOs (with hysteresis), watchdog and VCC Power GOOD.
An internal circuit provides an OR-wired not latched common (FAULT) indicator signaling the channel OVT. The (PGOOD) diagnostic pin is activated if VCC goes below the power good internal threshold. Both (FAULT) and (PGOOD) pins are open drain, active low, fault indication pins.Key Features
