7.3 Feature Description

The ISOM8610 is a current controlled isolated switch, and is a reliable pin-to-pin replacement of to existing Opto-MOS devices in DFG package. The isolated switch is normally open, which means the switch on secondary side is in OFF state when the primary LED emulator current is lower than the input trigger current level. In the OFF state, the back-to-back MOSFETs on the secondary side block up to 80V of difference between S1 and S2. Once the primary side LED emulator current goes above input trigger current, the switch on the secondary side turns ON. During the ON state, the secondary side back-to-back FETs can conduct currents up to 150mA. The robust SiO2 dielectric isolation in the ISOM8610 provides best in class isolation performance, faithfully withstanding 3750VRMS isolation ratings between side 1 and side 2, performance limited by package clearance.
