The STMicroelectronics ISO808x Galvanic Isolated 8-Channel Drivers are designed to drive any load with one side connected to the ground and are now offered by Mouser. Two distinct galvanic isolated voltage domains are included in each driver (VCC and VDD for the process and control logic stages). These drivers offer low supply current, a maximum 45V process stage supply voltage, a typical RDS(ON) of 0.125 Ohm per channel, disabled reset for IC outputs, excellent common mode transient immunity, and output channel short circuit protection. The drivers additionally include case over-temperature protection, per-channel over-temperature protection with thermal independence of individual channels, over-voltage protection, and loss of GND and VCC safeguards.
The drivers include an additional case temperature sensor that guards against overheating of the whole chip (OVC event). Channels that aren’t overwhelmed keep operating normally. Loss of ground protection, VCC and VDD UVLOs (with hysteresis), and watchdog-embedded functions are some of these factors. All loads, including resistive, capacitive, and conductive ones, as well as programmable logic controllers, industrial PC peripheral input/output devices, and numerical control machines, may be handled by the devices.
