O
When power down, outputs VSS(0V, typ).
Negative Voltage Output Pin
Connect to VSS1 with a 1.0μF capacitor which is low ESR (Equivalent
13
Series Resistance) over all temperature range. When this capacitor has the
VEE
O
polarity, the positive polarity pin must be connected to the VSS1 pin. Non
polarity capacitors can also be used.
Negative Charge Pump Capacitor Terminal Pin
Connect to CP with a 1.0μF capacitor which is low ESR (Equivalent Series
14
Resistance) over all temperature range. When this capacitor has the polarity,
CN
I
the positive polarity pin must be connected to the CP pin. Non polarity
capacitors can also be used.
Positive Charge Pump Capacitor Terminal Pin
Connect to CN with a 1.0μF capacitor which is low ESR (Equivalent Series
15
Resistance) over all temperature range. When this capacitor has the polarity,
CP
I
the positive polarity pin must be connected to the CP pin. Non polarity
capacitors can also be used.
