TCAN1043-Q1: Difference between TCAN1043-Q1 and TCAN1042-Q1

Hi Fery,

thanks for reaching out! These devices are quite similar regarding some parameters like: they both support CAN and CAN FD (flexible data rate), have 1 channel, wide supply voltage range (4.5V to 5.5V), Bus Fault Voltage (-58V to 58V), Common Mode Voltage (-30V to 30V).
Although these devices share some common similarities, their feature set is quite different as a matter of fact the TCAN1043-Q1 has 14 pins while the TCAN1042-Q1 is an 8 pin device.
Since the TCAN1043 has more pins, that means it also offers more features. In fact it has not only the TXD, GND, VCC, RXD, STB, CANH, CANL, NC/Vio pins like the TCAN1042 but also presents:
-Vsup (battery supply input),
- WAKE (wake input, high voltage)
-nFAULT (fault output for Bus fault protection, inverted logic)
-INH (inhibit pin is used to control system voltage regulators, high voltage output)
-EN (enable pin for mode control, has integrated pull down)
-VIO (voltage to supply the I/O)

In addition to this, the TCAN1043-Q1 offers Ultra low power Standby Mode and Low Power Silent Mode and Sleep Mode, ±10kV HBM ESD and ±8kV IEC for bus pins whereas the TCAN1042-Q1 has only Standby Mode, ±16 kV HBM ESD and ±15kV IEC for bus pins.

Fery, these are some of the differences between the two devices; let me know if this helps and if you need specific parameters, like electrical characteristics.

Thank you and best regards,
Adrian
