Description

General part information

ISO808-1 Series

The ISO808, ISO808-1 (PowerSO-36) and ISO808Q, ISO808Q-1 (TFQFPN32) are galvanic isolated 8-channel drivers featuring a low supply current. Each driver contains 2 independent galvanic isolated voltage domains (VCC and VDD for the Process and Control Logic stages, respectively). The ICs are intended for driving any kind of load with one side connected to ground.

Active channel current limitation (OVL) combined with thermal shutdown (OVT), independent for each channel, protects the device against overload.

Built-in thermal shutdown protects each channel from overtemperature and overload: each overheated channel automatically turns OFF after its junction temperature triggers the protection threshold (TJSD). The channel turns back ON if its junction temperature decreases lower than restart threshold (TJR).
