PARIS Holt Integrated Circuits has launched the HI-3000H, a family of CAN transceivers that can operate in temperatures from -55°C to 200°C. Compatible with ARINC 825 and ISO 11898-5 standards, the HI-3000H is suitable for high temperature avionics and industrial applications such as aircraft braking systems, engine controls and down-hole drilling.
Holt said the HI-3000H supports two modes of operation, namely the Normal Mode and the Standby Mode. The Standby Mode is a very low-current mode which continues to monitor bus activity, allowing the external controller to manage wake-up. Superior common-mode receiver performance makes the device suitable for applications where ground reference voltages may vary from point to point over long distances along the CAN bus.
The HI-3000H provides a SPLIT pin to give an output reference voltage of VDD/2 which can be used for stabilizing the recessive bus level when the split termination technique is used to terminate the bus.
