STMicroelectronics ISO808A-1
The ISO808A, ISO808A-1 (PowerSO-36) and ISO808AQ, ISO808AQ-1 (TFQFPN32) are galvanic isolated 8channel 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.| Part No. | ISO808A-1 |
