MAX33012EASA+

MAX33012EASA+ is a +5V CAN (control area network) transceiver with integrated protection for industrial applications. This device has extended ±65V fault protection on the CAN bus for equipment where overvoltage protection is required. It incorporates high ±45kV ESD HBM protection and an input common mode range (CMR) of ±25V, exceeding the ISO11898 specification of -2V to +7V, and well suited for applications where ground planes from different systems are shifting relative to each other. This device incorporates a fault detection feature where it monitors the CANH and CANL line for faults like overcurrent, overvoltage, and transmission failure. When a fault is detected, the FAULT pin goes high, which triggers an external interrupt with the local CAN controller, and the driver and receiver lines are placed in recessive mode. It is used in applications such as industrial automation, building automation, vending machines, security systems, heavy equipment machinery.

• Transmitter dominant timeout prevents lockup, short-circuit protection limits driver current
• Thermal shutdown, detects overcurrent, overvoltage, and transmission failure
• Error code reporting through RXD, supply voltage range from 4.5V to 5.5V
• Dominant supply current is 5mA typical at (VDD = 4.5V to 5.5V, VL = 1.62V to VDD)
• Standby supply current is 60μA typical at (VDD = 4.5V to 5.5V, VL = 1.62V to VDD)
• Input resistance is 50Kohm maximum at (VDD = 4.5V to 5.5V, VL = 1.62V to VDD)
• Input leakage current is 150μA typical at (VDD = VL = 0V, CANH = CANL = VDD)
• Input capacitance is 22pF typical at (VDD = 4.5V to 5.5V, VL = 1.62V to VDD)
• Slow slew driver rise time is 160ns typical at (RL = 60 ohm, CLD = 100pF, RCM is open)
• Operating temperature range from -40°C to +125°C, 8-pin SO package
