MAX33040E/MAX33041E +3.3V, 5Mbps CAN Transceiver with 40V Fault Protection, 25V CMR, and 40kV ESD in 8-Pin SOT23 General Description Benefits and Features The MAX33040E/MAX33041E are +3.3V control area net- Integrated Protection Increases Robustness work (CAN) transceivers with integrated protection for in- Increased Protection on CANH and CANL dustrial applications. These devices have extended 40V 40V Fault Tolerant fault protection on CANH and CANL for equipment where 40kV ESD Human Body Model (HBM) overvoltage protection is required. They also incorporate Protection high 40kV ESD HBM and an input common-mode range 25V Extended Common-Mode Input Range (CMR) of 25V on CANH and CANL, exceeding the ISO (CMR) 11898-2 CAN standard of -2V to +7V. This makes these Short-Circuit Protection parts well suited for applications where there is moderate Transmitter Dominant Timeout Prevents Lockup electrical noise that can influence the ground levels be- Thermal Shutdown tween two nodes or systems.
