High-speed CAN Transceiver

The ATA6660 is a monolithic circuit based on the Atmel’s Smart Power BCD60-III technology. It is especially designed for high speed CAN-Controller CAN-C differential mode data transmission between CAN-Controllers and the physical differential bus lines.

Overcurrent Protection

The ATA6660 is a monolithic circuit based on Atmel’s Smart Power BCD60-III technology. It is especially designed for high-speed differential mode data transmission in harsh environments like automotive and industrial applications. Baudrate can be adjusted up to 1 Mbaud. The ATA6660 is fully compatible to the ISO11898, the developed standard for high speed CAN-C Controller Area Network communication.

High voltage protection circuitry on both line pins, CANH Pin 7 and CANL Pin 6 , allow bus line voltages in the range of -40 V to +40 V. ESD protection circuitry on line pins allow HBM = 8 kV, MM = 300 V. The implemented high voltage protection on bus line output/input pins 7/6 makes the ATA6660 suitable for 12 V automotive applications as well as 24 V automotive applications.

A fixed slope is adjusted to prevent unsymmetrical transients on bus lines causing EMC problems. Controlled bus lines, both CANH and CANL signal, will reduce radio frequency interference to a minimum. In well designed bus configurations the filter design costs can be reduced dramatically.

In the case of a line shorts, like CANH to GND, CANL to VCC, integrated short current limitation allows a maximum current of ICANH_SC or ICANL_SC. If junction temperature rises above 165°C an internal overtemperature protection circuitry shuts down both output stages, the receiver will stay activated.
