"GIFT is a joint project between the automotive and semiconductor industries that aims to create a specification for a CAN transceiver module in such a way that technical interoperation of devices from different manufacturers is possible," said Bob Klosterboer, AMI’s senior vice president of integrated mixed-signal products.

AMI’s device is said to combine low power operation with high tolerance to electrostatic discharge (ESD) and electromagnetic interference (EMI). It operates with a typical supply current of 3.7 mA. Sleep, standby and power-on standby modes further reduce power consumption when the transceiver is inactive. In sleep mode, total power consumption is typically 35 ìA. Wake-up can be controlled via bus lines, power-on reset flag outputs and edge-sensitive wake-up input.

Klosterboer said the new CAN chip includes a built-in slope control function with excellent differential output matching drivers to realize very low electromagnetic emissions. A fully integrated differential receiver filter with a wide common-mode range ensures high EMI tolerance. The firm’s high-power, mixed-signal semiconductor processes result in ESD ratings of ±8 kV human body model (HBM) on all high-voltage pins, as well as providing protection against short circuit and reverse battery conditions.
