10 Power Supply Recommendations

The TCAN1057AEV-Q1 transceiver is designed to operate with a main V_CC input voltage supply range between 4.5 V and 5.5 V. The TCAN1057AEV-Q1 implements an I/O level shifting supply input, V_IO, designed for a range between 1.7 V and 5.5 V. It is important that both supply inputs are well regulated. In addition to the power supply filtering capacitance, a decoupling capacitance that is typically 100 nF should be placed near the CAN transceiver's V_CC and V_IO supply pins.
