PRODUCTION DATA
Table 10-1 lists the supply configuration for these devices:
INPUTS | OUTPUTS | ||||
---|---|---|---|---|---|
VDD | VIO | EN/FLT | BUS OUTPUT (CANH/CANL) | RXD | VISOOUT(2) |
< VDD(UVLO+) | >VIO(UVLO+) | X | High-Z | Recessive (Default High) | OFF |
>VDD(UVLO+) | <VIO(UVLO+) | X | High-Z | Recessive (Default High) | Invalid Operation |
5 V | 1.71 V to 5.5 V | H or Open | Per Device Mode (1) and TXD | Mirrors Bus | 5 V |
5 V | 1.71 V to 5.5 V | L | High-Z | Recessive (Default High) | OFF |
Table 10-2 shows the different driver functional modes:
INPUTS | OUTPUTS | ||||||
---|---|---|---|---|---|---|---|
VDD(1) | VIO | EN/FLT | STB | INPUT TXD | CANH (3) | CANL (3) | DRIVEN BUS STATE |
PU | PU | H or Open | L | L | H | L | Dominant |
H or Open | Z | Z | Recessive | ||||
H or Open | X | Hi-Z | Hi-Z | Weak pull-down to ground | |||
L | X | X | Hi-Z | Hi-Z | Weak pull-down to ground | ||
PD | PU | X | X | X | Hi-Z | Hi-Z | Weak pull-down to ground |
PU | PD(2) | X | X | X | Invalid Operation |
At Normal mode (STB = L), the CAN outputs follow the logic states at data input, TXD. A logic low at the TXD input causes the CAN output to go dominant. Therefore the differential output voltage defined by Equation 2 is positive. A logic high at the TXD input causes the CAN BUS to go recessive. Therefore the differential output voltage defined by Equation 2 is negative.
At Standby mode (STB = H or Open), both outputs go to the high-impedance (Hi-Z) state. The logic state at the TXD pin is irrelevant when this mode. The driver is disabled (bus outputs are in the Hi-Z) by default when the STB pin is left open. The TXD pin has an internal pullup resistor.
Table 10-3 shows the different receiver functional modes:
INPUTS | OUTPUT | |||||
