3.3V Radiation Tolerant CAN Transceiver with Listen Mode and Loopback

The Intersil ISL72026SEH is a radiation tolerant 3.3V CAN

Features

transceiver that is compatible with the ISO11898-2 standard

• Electrically screened to SMD 5962-15228

for applications calling for Controller Area Network (CAN) serial

communication in satellites and aerospace communications

and telemetry data processing in harsh industrial

environments.

• ESD protection on all pins. . . . . . . . . . . . . . . . . . . . . .4kV HBM

• Compatible with ISO11898-2

• Operating supply range . . . . . . . . . . . . . . . . . . . . . 3.0V to 3.6V

• Bus pin fault protection to ±20V

The transceiver can transmit and receive at bus speeds up to

5Mbps. It can drive a 40m cable at 1Mbps per the ISO11898-2

specification. The device is designed to operate over a

• Undervoltage lockout

common-mode range of -7V to +12V with a maximum of 120

nodes. The device has three discrete selectable driver rise/fall

time options, a listen mode feature and loopback test capability.

• Cold spare: powered down devices/nodes will not affect

active devices operating in parallel

• Three selectable driver rise and fall times

• Glitch free bus I/O during power-up and power-down

• Full fail-safe (open, short, terminated/undriven) receiver

• Hi Z input allows for 120 nodes on the bus

• High data rates. . . . . . . . . . . . . . . . . . . . . . . . . . . up to 5Mbps

• Quiescent supply current . . . . . . . . . . . . . . . . . . . . 7mA (max)

• Listen mode supply current . . . . . . . . . . . . . . . . . . 2mA (max)

• -7V to +12V common mode input voltage range

• 5V tolerant logic inputs

Receiver (Rx) inputs feature a “full fail-safe” design, which

ensures a logic high Rx output if the Rx inputs are floating,

shorted, or terminated but undriven.

The ISL72026SEH is available in an 8 Ld hermetic ceramic

flatpack and die form that operate across the temperature

range of -55°C to +125°C. The logic inputs are tolerant with

5V systems.

Other CAN transceivers available are the ISL72027SEH and

ISL72028SEH. For a list of differences see Table 1 on page 2.
