4. Power Supply
The EM6617-1 is supplied by a single external power supply between V
DD
(Vbat) and V
SS
(ground). A built-in
voltage regulator generates Vreg providing regulated voltage for the oscillator and the internal logic. The output
drivers and the ADC are supplied directly from the external supply VDD. A typical power connection
configuration and the internal power connection is shown below.
