“L”: DV18 is Output pin, “H”: DV18 is Power Supply Pin
Digital Power Pin, Typ 1.8V
VSEL=”L”, Output
When the PDN pin= “L”, the DV18 pin outputs “L”. Current must not be

I/O taken from this pin. A 10μF (±30%; including the temperature
*
characteristics) capacitor should be connected between this pin and
DVSS. When this capacitor is polarized, the positive polarity pin should be
connected to the DV18 pin.

- Digital Power Supply Pin, 3.0  3.6V or 1.7  1.9V
47 NC
- This pin must be connected to DVSS.
48 NC
- This pin must be connected to DVSS.
Note 1. All input pins must not be allowed to float. DVDD must be connected to the same power supply.
Note 2. S_PB, CM3-0, OBOT1-0, TDM, ODIF1-0, IDIF2-0 and CAD1-0 pin must be changed when the
PDN pin =”L”.
