1. For Vsupply lower than 21 V an external resistor between Vsupply and Vsupply Int pins are required.
For Vsupply lower than 15 V external diodes for charge pump are required.
2. Operating supply current is measured with system regulators operating but not loaded.
3. Operating VGPIO_SPI current is measured with all circuits supplied by VGPIO_SPI (GPIO’s, operational
amplifiers and pass switches) enabled but not loaded.
4. The external components connected to the pin must be chosen to avoid that the voltage exceeds this
operative range.
