4.4 Power Control IP

The TCAN1164-Q1 contains several circuit blocks that are responsible for internal power management of the device. The power control unit encompasses two internal regulators to generate a 5V and 1.5V supply, from the VSUP supply, for the analog and digital circuitry needed for the device to operate. The power control unit contains a bandgap voltage and current reference to provide biasing to the internal analog circuits. There is an oscillator inside the device that generates clock signals that operate the digital core in a synchronous fashion.
