1Mbps CAN Transceiver with
Low Power Standby Mode
GENERAL DESCRIPTION
The HI-5000 is a 1 Mbps Controller Area Network (CAN)
transceiver. It interfaces between a CAN protocol con-
troller and the physical wires of the bus in a CAN network.
Differential output amplitude and current drive capability
are specifically enhanced to meet the needs of long cable
runs typical in many applications such as industrial auto-
mation.
The HI-5000 supports two modes of operation: Normal
Mode and Standby Mode. The Standby Mode is a very
low-current mode which continues to monitor bus activity
and allows an external controller to manage wake-up.
Superior common-mode receiver performance makes
the device especially suitable for applications where
ground reference voltages may vary from point to point
over long distances along the CAN bus. In addition, the
HI-5000 provides a SPLIT pin to give an output reference
voltage of VDD/2 which can be used for stabilizing the re-
cessive bus level when the split termination technique is
used to terminate the bus.
A TXD dominant time-out feature also protects the bus
from being driven into a permanent dominant state (so-
called “babbling idiot”) if pin TXD becomes permanently
low due to application failure.
The device also has short circuit protection to +/-58V on
CANH, CANL and SPLIT pins and ESD protection to
+/- 6kV on all pins.
The HI-5001 is identical to the HI-5000 except the SPLIT
pin is substituted with a VIO supply voltage pin. This al-
lows the HI-5001 to interface directly with controllers with
2.5V or 3.3V supply voltages.
The HI-5002 provides both the SPLIT and VIO supply
voltage pins in a compact 16-pin QFN.
All three devices are available in industrial -40^oC to +85^oC
temperature ranges. “RoHS compliant” lead-free options
are also available.

FEATURES
· Compatible with ISO 11898-5 standard.
· Signaling rates up to 1Mbit/s.
· Internal VDD/2 voltage source available to stabilize the
recessive bus level if split termination is used (HI-5000
SPLIT pin).
· VIO input on HI-5001 allows for direct interfacing with 2.5V
or 3.3V controllers.
· Detection of permanent dominant on TXD pin (babbling
idiot protection).
· High impedance allows connection of up to 120 nodes.
· CANH, CANL and SPLIT pins short-circuit proof to +/-58V.
· Will not disturb the bus if unpowered.
