Galvanic isolated eight-channel drivers are ideal for all types of loads

STMicroelectronics ISO808x Galvanic Isolated 8-Channel Drivers, available now from Mouser, are intended to drive any load with one side connected to the ground. Each driver comprises two independent galvanic isolated voltage domains (VCC and VDD for the process and control logic stages). These drivers provide a low supply current, maximum 45V process stage supply voltage, 0.125-Ohm ON state resistance per channel (typical) RDS(ON), reset function for IC outputs disabled, high common mode transient immunity, and short circuit protection on output channels. The drivers also offer per-channel over-temperature protection with thermal independence of separate channels, case over-temperature protection, over-voltage protection, and loss of GND and VCC protections.

The drivers incorporate an extra case temperature sensor that protects the whole chip against overtemperature (OVC event). Non-overloaded channels continue to function normally. These drivers include loss of ground protection, VCC and VDD UVLOs (with hysteresis), and watchdog-embedded functions.

The devices are suitable for all loads, including resistive, capacitive and conductive, and programmable logic control, industrial PC peripheral input/output, and numerical control machines.
