LTC2875HS8#PBF Visão geral
What is a CAN transceiver? A CAN transceiver is an interface IC that sits between a CAN protocol controller (typically a microcontroller) and the physical differential two-wire CAN bus (CANH/CANL). It converts the controller's CMOS/TTL TX/RX logic into the differential dominant/recessive signaling required by ISO 11898-2/ISO 11898-5, providing ESD and overvoltage robustness, common-mode rejection, and the bus-level protection that the controller itself cannot supply. The LTC2875 belongs to the interface IC -> transceiver IC -> CAN bus transceiver category inside the broader CAN bus driver / CAN FD transceiver family.
Key features include ±60V bus fault protection, ±25kV ESD (HBM) on the CANH/CANL pins, ISO 11898-2 and ISO 11898-5 conformance, low current shutdown mode, SPLIT pin for recessive stabilization, and a wide supply range of 3V to 5.5V. The driver output stage is internally slew-rate limited and guarantees VSYM (driver symmetry) so the part can be used in CAN FD frames up to 4 Mbps.
The LTC2875 combines an NPN/PNP bipolar bus driver with a precision differential receiver and a charge-pump-assisted protection rail that clamps bus voltages above and below the supply rails. The integrated ±60V fault path is active even in shutdown and power-off states, an important differentiator versus conventional CAN transceivers that lose protection when VCC collapses.
Typical applications include automotive body and chassis ECUs, industrial CAN nodes with long cabling exposed to 24V/48V supply transients, building automation and HVAC CAN networks, and any 3.3V or 5V MCU-based system that must survive miswiring or load-dump events on the bus.
When designing with this part, place 100nF supply decoupling as close as possible to VCC and add TVS diodes (or use the part's integrated ±60V clamp) to guarantee fault survival. The SPLIT pin typically requires a 10kΩ/1nF RC network to ground for proper recessive-bias stabilization per the datasheet typical application circuit.

Aplicações típicas
LTC2875HS8#PBF é adequado para 6 aplicaçãos: Automotive Body and Chassis ECU CAN Node, Industrial 24V/48V CAN Bus Node, Building Automation / HVAC CAN Network, Battery Management System (BMS) CAN Interface, Medical Equipment CAN Interface, Agricultural / Off-Road Vehicle CAN Bus.
Automotive Body and Chassis ECU CAN Node
The LTC2875HS8#PBF's ±60V bus fault protection and ±25kV ESD rating make it ideal for automotive body and chassis ECUs exposed to load-dump transients on 12V/24V battery rails. Placed between a 3.3V MCU CAN controller and the differential CANH/CANL bus, the part survives miswiring events up to 60V without external TVS diodes. Per the Analog Devices LTC2875 datasheet, the integrated protection is active even in power-down, a critical advantage for ECU sleep-mode power states where conventional CAN transceivers lose bus protection. The 4 Mbps CAN FD capability supports next-generation body-domain networks.
Recomendado
Industrial 24V/48V CAN Bus Node
In factory automation and process control, 24V/48V supply rails frequently produce transient events that damage conventional CAN transceivers. The LTC2875HS8#PBF's ±60V fault clamp eliminates the need for upstream TVS protection, reducing BOM and PCB area. With 4 Mbps CAN FD support and ISO 11898-2/5 compliance, the part integrates directly into industrial PLCs, drives, and sensor nodes that communicate over CANopen or DeviceNet. Per the Analog Devices datasheet, the SPLIT pin's recessive stabilization guarantees signal integrity on long bus segments typical of factory floors.
Recomendado
Building Automation / HVAC CAN Network
HVAC controllers and building automation nodes frequently run long CAN bus cables through walls and cable trays, where fault exposure (miswiring to 24V mains) is high. The LTC2875HS8#PBF's integrated ±60V bus fault tolerance allows these nodes to survive installer miswiring without board damage. Per the Analog Devices LTC2875 datasheet, the 3V-5.5V VCC range supports both legacy 5V MCUs and modern 3.3V controllers common in thermostat and VAV controller designs. ISO 11898-5 driver symmetry ensures CAN FD compatibility for next-gen BMS protocols.

Battery Management System (BMS) CAN Interface
Battery management systems for EVs and stationary storage use CAN to report cell voltages, temperatures, and state-of-charge. The LTC2875HS8#PBF's ±60V fault clamp protects the BMS CAN interface from high-voltage transients when stacked battery packs exceed standard 12V/24V levels. Per the Analog Devices datasheet, the part's wide common-mode range (±25V) handles the large ground potential differences in stacked-cell battery architectures. The low-power shutdown mode supports BMS sleep currents while still providing fault protection during vehicle storage.
Recomendado
Medical Equipment CAN Interface
Medical device CAN networks (patient monitors, infusion pumps, lab analyzers) require fault-tolerant communications in electrically noisy environments. The LTC2875HS8#PBF's ±60V bus fault tolerance and ±25kV ESD protect medical CAN nodes from electrocautery, defibrillator, and other in-room transients. Per the Analog Devices LTC2875 datasheet, the 8-SO package and -40C to +125C operating range suit portable and bedside medical equipment. The integrated protection reduces BOM and helps meet IEC 60601 EMC compliance targets by eliminating external TVS assemblies.
Recomendado
Agricultural / Off-Road Vehicle CAN Bus
Agricultural and construction machinery operate in 24V systems with frequent load-dump events from alternator switching. The LTC2875HS8#PBF's ±60V fault clamp tolerates these events without external protection, reducing field failures. Per the Analog Devices datasheet, the -40C to +125C operating range suits underhood and exposed-mount ECUs on tractors, harvesters, and excavators. The 4 Mbps CAN FD rate supports precision-agriculture telemetry busses that aggregate GPS, yield, and sensor data.

Notas de projeto
VCC decoupling is critical for the LTC2875HS8#PBF: place a 100nF X7R ceramic capacitor within 2mm of the VCC pin, in parallel with a 1uF bulk capacitor. The internal high-voltage fault clamp draws transient current from VCC during bus fault events; inadequate VCC decoupling can collapse the rail and trigger false bus errors. Per the Analog Devices datasheet, add a 1uF/10V ceramic close to VCC in fault-exposed automotive designs.
Route CANH and CANL as a tightly coupled differential pair with 100Ω characteristic impedance, matching the LTC2875HS8#PBF's bus termination. Keep bus traces symmetric and short, and place the SPLIT pin's 10kΩ/1nF RC network within 5mm of pin 8. Ground the SPLIT network's return to the LTC2875's GND pin, not the chassis, to avoid ground loops per the Analog Devices application schematic.
Do not omit the SPLIT-pin RC network on the LTC2875HS8#PBF: without it, the recessive common-mode voltage floats and CAN bit error rates increase. Do not connect SPLIT directly to ground - this prevents the part's internal recessive-bias circuit from stabilizing the bus. Also, never apply a 24V rail directly to the bus without external TVS if the upstream fuse is rated above 1A; the LTC2875's ±60V clamp is rated to handle load-dump transients, but sustained overcurrent events will damage the package.
Add a small common-mode choke (e.g., 100uH) in series with the CANH/CANL bus lines to improve EMI margin on long bus segments. The LTC2875HS8#PBF's symmetric driver stage (VSYM guaranteed per ISO 11898-5) suppresses radiated emissions, but a choke plus 22pF capacitor across CANH/GND and CANL/GND provides additional protection for automotive EMC compliance (CISPR 25) per the Analog Devices application note.
