Product data sheet COMPANY PUBLIC Rev. 1.0 — 15 June 2016 13 of 85 NXP Semiconductors OL2385 Industrial RF transceiver [1] Voltage ranges are given here only for information purpose. Please refer to the electrical characteristics for detailed voltage range specification. The external power supply domains with the associated power supply pins are briefly described in the Table 5. The package HVQFN has an exposed die pad at the back which is intended as heat sink and additional ground connection. The device includes an internal power regulator which can be used to generate a voltage less than 3.6 V when such a voltage is not available. This regulator utilizes the two supply pins VDD_5VIN and VDD_3VOUT. The regulator is only on if the device is in power supply state ACTIVE. In all other power supply states the regulator is off. VDD_5VIN can be supplied permanently and the input voltage must be greater than 3.6 V. The application has to ensure that the current drawn from the internal power regulator does not exceed the maximum limit given in the section electrical characteristics. If this limit is exceeded all supply voltage pins in the 3 V domain must be connected to an external voltage regulator. It is not allowed to supply parts of the device with the internal and other ones with an external 3 V supply. VDD_DIG, GND_DIG 3 V Power supply for the digital part. VDD_5VIN 5 V Supply voltage input for the internal power regulator. This regulator generates the required supply voltage for the device’s VDD supply pins in the 3 V domains. VDD_3VOUT 3 V Regulated supply voltage output of the internal power regulator. Table 5. External power supply domains Power supply pin Voltage range Description |
