ISO8200B Datasheet PDF - ST Microelectronics

The ISO8200B is a galvanic isolated 8-channel high-side smart power Solid State Relay Driver featuring a very low supply current. It contains 2 independent galvanic isolated voltage domains (Vcc for the Power stage and Vdd for the Digital stage). Additional embedded functions are loss of GND protection, undervoltage shutdown with hysteresis and reset function for immediate power output shutdown. The IC is intended to drive any kind of load with one side connected to ground. Active channel current limitation combined with thermal shutdown, (independent for each channel) and automatic restart, protect the device against overload and short-circuit. In overload conditions, if junction temperature overtakes threshold, the channel involved is turned off and on again automatically after the IC temperature decreases below a reset threshold.
