Broadcom ACPL-M417T Optocouplers are single-channel, low-speed, and high-gain automotive optocouplers with transistor output. These optocouplers are designed for low-power operation, with a low-operating LED drive current of 0.3mA for low-speed signaling. The low collector dark current effectively does not consume any current when not in use. The ACPL-M417T optocouplers are AEC-Q101 qualified and come in a compact, surface-mountable SO4 package for space savings. These optocouplers provide an isolation voltage of 4kVRMS between input and output channels. The ACPL-M417T optocouplers provide reinforced insulation and reliability to deliver safe signal isolation in automotive and high-temperature industrial applications. Ideally, these optocouplers are used in Electric Vehicle (EV) powertrains, DC-DC converters, EV/PHEV chargers, HVAC, and fault-reporting modules.
