MCP25612FD Datasheet, PDF (1/26 Pages) Microchip Technology – Dual CAN Flexible Data-Rate Transceiver

MCP25612FD
Dual CAN Flexible Data-Rate Transceiver
Features
• Supports both “classic” CAN 2.0 and CAN FD
physical layer requirements
• Optimized for CAN FD (Flexible Data-Rate) at
2, 5 and 8 Mbps Operation:
- Maximum Propagation Delay: 120 ns
- Loop Delay Symmetry: -10%/+10% (2 Mbps)
• Implements ISO-11898-2 and ISO-11898-5
Standard Physical Layer Requirements
• Very Low Standby Current (5 µA per transceiver,
typical)
• Two Fully Independent V_DDX and V_SSX Pins per CAN
FD Transceiver for Added Flexibility and Reliability:
- Optimal for redundant CAN networks
• Compatible to 5V MCUs
• Functional Behavior Predictable Under All Supply
Conditions:
- Device is in Unpowered mode if V_DDX drops
below undervoltage level
- An unpowered node or brown-out event will
not load the CAN bus
• Detection of Ground Fault:
- Permanent dominant detection on T_XDX
- Permanent dominant detection on bus
• Power-on Reset and Undervoltage Lock-out on
V_DDX Pin
• Protection against Damage due to Short-Circuit
Conditions (positive or negative battery voltage)
• Protection against High-Voltage Transients in
Automotive Environments
• Automatic Thermal Shutdown Protection
• Suitable for 12V and 24V Systems
• Meets or exceeds Stringent Automotive Design
Requirements, including “Hardware Requirements
for LIN, CAN and FlexRay™ Interfaces in
Automotive Applications”, Version 1.3, May 2012:
- Conducted emissions @ 2 Mbps with
Common-Mode Choke (CMC)
- Direct Power Injection (DPI) @ 2 Mbps with CMC
• Meets SAE J2962/2 “Communication
Transceivers Qualification Requirements – CAN”:
- Passes radiated emissions at 2 Mbps without
a CMC
• High Noise Immunity due to Differential Bus
Implementation
• High ESD Protection on CANHx and CANLx,
Meets IEC61000-4-2, up to ±6 kV
• Available in 14-Lead SOIC
• Temperature Ranges:
- Extended (E): -40°C to +125°C
- High (H): -40°C to +150°C
Description
The MCP25612FD is a second generation, dual CAN
FD transceiver from Microchip Technology Inc. It offers
all of the features from two fully independent
MCP2561FD CAN transceivers, except for the SPLIT
pin. It ensures Loop Delay Symmetry in order to support
the higher data rates required for CAN FD. The maxi-
mum propagation delay is improved to support a longer
bus length.
The device meets the automotive requirements for CAN
FD bit rates, low quiescent current, robust
Electromagnetic Compatibility (EMC) and Electrostatic
Discharge (ESD).
