Fault-tolerant CAN transceiver

2.3 Protections

I Bus pins short-circuit safe to battery and to ground

I Thermally protected

I Bus lines protected against transients in an automotive environment

I An unpowered node does not disturb the bus lines

2.4 Support for low power modes

I Low current sleep mode and standby mode with wake-up via the bus lines

I Power-on reset flag on the output

3. Quick reference data

Table 1. Quick reference data

VCC = 4.75 V to 5.25 V; VBAT = 5.0 V to 27 V; VSTB = VCC; Tvj = −40 °C to +150 °C; all voltages are

defined with respect to ground; positive currents flow into the device; unless otherwise specified.[1][2]

[1] All parameters are guaranteed over the virtual junction temperature range by design, but only 100 % tested

at Tamb = 125 °C for dies on wafer level, and above this for cased products 100 % tested at Tamb = 25 °C,

unless otherwise specified.

[2] For bare die, all parameters are only guaranteed if the back side of the die is connected to ground.

[3] A local or remote wake-up event will be signalled at the transceiver pins RXD and ERR if

VBAT = 5.3 V to 27 V see Table 5.
