10 Power Supply Recommendations

10.1 VDD

The recommended VDD supply voltage range is 3 V to 5.5 V. The device requires approximately 2 mA (I(SUPP)) typical in normal operating mode and below 10 µA in sleep mode. If the VDD supply is not used, then it may be connected to AGND/GND.

10.2 VPWR

The recommended VPWR supply voltage range is 0 V to 25 V. The device requires approximately 2 mA (I(SUPP)) typical in normal operating mode and below 10 µA in sleep mode.
