GALVANIC ISOLATED 8 CHANNEL HIGH-SIDE SWITCH (0.6A PER CHANNEL)

This project provides 8 fully protected and isolated high-side power switches that are able to handle current up toΒ 625 mA. An 8-bit parallel microcontroller compatible interface allows connecting the inputs directly to a microcontroller or standalone circuit system. The input interface also supports direct control mode and is designed to operate withΒ 3.3/5V CMOSΒ compatible levels. The signal transfer from input to output side is realized by the integratedΒ Coreless Transformer Technology. The board is designed for industrial applications such as process control and PLC to drive inductive, resistive, and capacitive loads like Relay, solenoid, lamps, heaters, piezo.

The input can be driven by applyingΒ 3.3V/5V CMOSΒ compatible signals to connector CN1. It can operate in microcontroller Mode by using Chip Select and Write Signals or in Direct Control Mode by closing the JumperΒ J1 and J2Β and setting the Data Input fromΒ D0 to D7. The Output consists of 8 Channel High Side Switches withΒ 0.6AΒ Current rating. The Output is protected with a channel selectedΒ over-temperatureΒ switch (to off). The 8 high-side power switches are controlled by means of the integrated parallel interface. The interface is 8-bit ΞΌC compatible. Furthermore, a direct control mode can be selected that allows the direct control of the outputsΒ OP0…OP7Β by means of the inputsΒ D0…D7Β without any additional logic signal. TheΒ ΞΌCΒ compatible interface allows a direct connection to the ports of a microcontroller without the need for other components. Each of the 8 high-side power switches is protected against short toΒ +DC (VBB), overload, over-temperature, and against over-voltage by an active Zener clamp.
