3. Core Functional Features

High-speed Differential Transmission: Supports 1 Mbps data rate. Differential receiver suppresses common-mode noise, improves signal integrity, suitable for complex electromagnetic environments (e.g., near inverters and high-power motors)

Fault-tolerant Protection: Built-in CANH/CANL overvoltage/short-circuit protection, thermal shutdown circuit prevents overcurrent damage, suitable for high-voltage/interference scenarios in automotive and industrial applications

Multi-mode Operation: Supports high-speed mode, slope-control mode, standby mode with low-power standby current of only 1 mA, suitable for battery-powered devices

Permanent Dominant Detection: Detects TXD stuck low and disables CANH/CANL output drivers to prevent bus data corruption

Power-on Reset Protection: Upon powering on, CANH/CANL remains in high-impedance state to prevent bus communication interference at power-up.
