8.4 Power Supply Recommendations

The TCAN1472-Q1 transceiver is designed to operate with a main VCC input voltage supply range between 4.5V and 5.5V. The TCAN1472V-Q1 implements an I/O level shifting supply input, VIO, designed for a range between 1.8V and 5.5V. Both supply inputs must be well regulated. A decoupling capacitance, typically 100nF, should be placed near the CAN transceiver main VCC supply pin in addition to bypass capacitors. A decoupling capacitor, typically 100nF, should be placed near the CAN transceiver VIO supply pin in addition to bypass capacitors.
