| | | Automotive Optocouplers | | |
| | | |
| | | Most modern vehicles use communication media such as CANBus for data transmission and system control. In CANBus where transmission speed is up to 1Mbps, two 10MBd ACPL-M61T optocouplers in the CANBus interface are used for safe isolation such as in air-conditioner compressor controllers and battery management systems. Benefits • Wide operating temperature (-40°C to 125°C) meet AEC-Q100guidelines • HighCMR(30kV/usatVCM=1kV) • High reliabilitysuitableforautomotive applications • Low input LED drive current | | |
| | | Description Avago Technologies introduces a series of automotive optocouplers: ACPL-M43T and ACPL-M61T. These single channel, wide operating temperature, high CMR, high speed digital optocouplers in a five lead miniature footprint are specifically used in hybrid electric vehicle applications. These digital optocouplers have an improved version of the light emitting diode for lower input driving current thus, providing longer LED operating lifetime, lower power consumption and higher efficiency over a -40°C to +125°C temperature range. The typical circuit in the hybrid electric vehicle's motor inverter controller, DC-DC converter system, shows how the ACPL-M43T interfaces with the IPM module IGBT gate drive as well as fault detection isolation. | | |
