general description the max13050/max13052/max13053/max13054 are pin-for-pin compatible, industry-standard, high-speed, control area network (can) transceivers with extended ?0v fault protection. these products are ideal automo- tive and industrial network applications where overvoltage protection is required. these can transceivers provide a link between the can protocol controller and the physical wires of the bus lines in a can. these devices can be used for +12v/+42v battery, automotive, and devicenet applications, requiring data rates up to 1mbps. the can transceivers have an input common-mode range greater than ?2v, exceeding the iso11898 specification of -2v to +7v, and feature ?kv esd pro- tection, making these devices ideal for harsh automo- tive and industrial environments. the can transceivers provide a dominant timeout func- tion that prevents erroneous can controllers from clamp- ing the bus to a dominant level if the txd input is held low for greater than 1ms. the max13050/max13052 provide a split pin used to stabilize the recessive common- mode voltage. the max13052 also has a slope-control mode that can be used to program the slew rate of the transmitter for data rates of up to 500kbps. the max13053 features a silent mode that disables the trans- mitter. the max13053 also has a reference output that can be used to bias the input of older can controllers that have a differential comparator. the max13054 has a separate dedicated logic input, v cc2 , allowing interfacing with a +3.3v microcontroller. the max13050/max13052/max13053/max13054 are available in an 8-pin so package and are specified to operate in the -40? to +85? and the -40? to +125? temperature ranges. features ? fully compatible with the iso11898 standard ? 8kv esd iec 61000-4-2 contact discharge per ibee test facility ? 80v fault protection ? +3.3v logic compatible (max13054) ? high-speed operation of up to 1mbps ? slope-control mode (max13052) ? greater than 12v common-mode range ? low-current standby mode ? silent mode (max13053) ? thermal shutdown ? short-circuit protection ? transmit (txd) data dominant timeout ? current limiting ? split pin (max13050/max13052) max13050/max13052/max13053/max13054 industry-standard high-speed can transceivers with 80v fault protection ________________________________________________________________ maxim integrated products 1 ordering information 19-3598; rev 0; 2/05 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. part temp range pin-package max13050 esa -40? to +85? 8 so max13050asa/aut* -40? to +125? 8 so max13052 esa -40? to +85? 8 so max13052asa/aut* -40? to +125? 8 so max13053 esa -40? to +85? 8 so max13053asa/aut* -40? to +125? 8 so max13054 esa -40? to +85? 8 so max13054asa/aut* -40? to +125? 8 so selector guide part split slope control standby mode silent mode 3.3v supply ref pin-for-pin replacement max13050 yes yes tja1040 max13052 yes yes yes pca82c250/5-1 max13053 yes yes tja1050, amis-30660 max13054 yes yes tle6250v33, cf163 pin configurations, functional diagrams, and typical operating circuits appear at end of data sheet. +12v and +42v automotive devicenet nodes medium- and heavy-duty truck systems industrial applications * aut denotes introduction to aecq100 specifications. devicenet is a registered trademark of the open devicenet vendor association.

max13050/max13052/max13053/max13054 industry-standard high-speed can transceivers with 80v fault protection _______________________________________________________________________________________ 9 detailed description the max13050/max13052/max13053/max13054 ?0v fault-protected can transceivers are ideal for automotive and industrial network applications where overvoltage protection is required. these devices pro- vide a link between the can protocol controller and the physical wires of the bus lines in a control area network (can). these devices can be used for +12v and +42v battery automotive and devicenet applications, requir- ing data rates up to 1mbps. the max13050/max13052/max13053/max13054 dominant timeout prevents the bus from being blocked by a hungup microcontroller. if the txd input is held low for greater than 1ms, the transmitter becomes dis- abled, driving the bus line to a recessive state. the max13054 +3.3v logic input allows the device to com- municate with +3.3v logic, while operating from a +5v supply. the max13050 and max13052 provide a split dc-stabilized voltage. the max13053 has a reference output that can be used to bias the input of a can con- troller? differential comparator. all devices can operate up to 1mbps (high-speed mode). the max13052 slope-control feature allows the user to program the slew rate of the transmitter for data pin description pin max13050 max13052 max13053 max13054 name function 1 1 1 1 txd transmit data input. txd is a cmos/ttl-compatible input from a can controller with a 25k ? pullup to v cc . for the max13054, txd is pulled to v cc 2. 2 2 2 2 gnd ground 33 3 3 v cc supply voltage. bypass v cc to gnd with a 0.1? capacitor. 4 4 4 4 rxd receive data output. rxd is a cmos/ttl-compatible output from the physical bus lines canh and canl. for the max13054, rxd output voltage is referenced to the v cc 2 supply voltage. 5 5 split common-mode stabilization output. output equaled to 0.5 x v cc . split goes high impedance in standby mode . 6 6 6 6 canl can bus-line low 7 7 7 7 canh can bus-line high 8 8 stby standby input. drive stby low for high-speed operation. drive stby high to place the device in low-current standby mode. ? rs mode-select input. drive rs low or connect to gnd for high-speed operation. connect a resistor between rs and gnd to control output slope. drive rs high to put into standby mode. 5 ref reference output voltage. always on reference output voltage, set to 0.5 x v cc. 8 s silent-mode input. drive s low to enable txd and to operate in high-speed mode. drive s high to disable the transmitter. 5 v cc 2 logic-supply input. v cc 2 is the logic supply voltage for the input/output between the can transceiver and microprocessor. v cc 2 allows fully compatible +3.3v logic on all digital lines. bypass to gnd with a 0.1? capacitor. connect v cc 2 to v cc for 5v logic compatibility.

max13050/max13052/max13053/max13054 industry-standard high-speed can transceivers with 80v fault protection ______________________________________________________________________________________ 11 (figure 3). the transmitter becomes enabled upon detecting a rising edge at txd. receiver the receiver reads differential inputs from the bus lines (canh, canl) and transfers this data as a single- ended output (rxd) to the can controller. it consists of a comparator that senses the difference v diff = (canh - canl) with respect to an internal threshold of 0.7v. if this difference is positive (i.e., v diff > 0.7), a logic-low is present at rxd. if negative (i.e., v diff < 0.7v), a logic-high is present. the canh and canl common-mode range is greater than ?2v. rxd is logic-high when canh and canl are shorted or terminated and undriven. +3.3v logic compatibility (max13054) a separate input, v cc 2, allows the max13054 to com- municate with +3.3v logic systems while operating from a +5v supply. this provides a reduced input voltage threshold to the txd and stby inputs, and provides a logic-high output at rxd compatible with the microcon- troller? system voltage. the logic compatibility elimi- nates longer propagation delay due to level shifting. connect v cc 2 to v cc to operate the max13054 with +5v logic systems. driver output protection the current-limiting feature protects the transmitter out- put stage against a short circuit to a positive and nega- tive battery voltage. although the power dissipation increases during this fault condition, current-limit pro- tection prevents destruction of the transmitter output stage. upon removal of a short, the can transceiver resumes normal operation. thermal shutdown if the junction temperature exceeds +165?, the driver is switched off. the hysteresis is approximately 13?, txd rs canh canl bus state rxd low v rs 0.75 x v cc high low dominant low high or float v rs 0.75 x v cc v cc / 2 v cc / 2 recessive high xv rs 0.75 x v cc r icm to gnd r icm to gnd recessive high txd rs canh canl bus state rxd low v s < 0.8v high low dominant low high or float v s < 0.8v v cc / 2 v cc / 2 recessive high xv s > 2v v cc / 2 v cc / 2 recessive high table 2. transmitter and receiver truth table (max13052) txd stby canh canl bus state rxd low v stby 0.8v *v stby 0.3 x v cc 2 high low dominant low high or float v stby 0.8v *v stby 0.3 x v cc 2 v cc / 2 v cc / 2 recessive high x v stby 2v *v stby 0.7 x v cc 2 r icm to gnd r icm to gnd recessive high table 3. transmitter and receiver truth table (max13053) (max13050/max13054) transmitter disabled transmitter enabled t dom txd v canh - v canl figure 3. transmitter dominant timeout timing diagram * for the max13054
