The VNI8200XP is an octal high-side smart power Solid-state Relay with serial/parallel selectable interface on-chip. 8-channel Monolithic Driver featuring a very low supply current, with integrated SPI interface and high efficiency 100mA micropower step-down switching regulator peak current control loop mode. The IC, realized in STMicroelectronics? VIPower? technology 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. Additional embedded functions are loss of GND protection that automatically turns off the device outputs in case of ground disconnection, undervoltage shutdown with hysteresis.
