1. For V
supply
lower than 21 V an external resistor between V
supply
and V
supply Int
pins are required.
For V
supply
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 V
GPIO_SPI
current is measured with all circuits supplied by V
GPIO_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.
