CP2

I

Positive Charge Pump Capacitor Terminal Pin 2

Connect to CN2 with a 2.2

μF capacitor that should have the low ESR (Equivalent

Series Resistance) over all temperature range. When this capacitor has the polarity, the

positive polarity pin should be connected to the CN2 pin. Non polarity capacitors can

also be used.

* The maximum bias voltage of this pin is 7.2V. The capacitance variation of an

external capacitor should be in the range of 2.2

μF +20% and -40% including the

difference by a tolerance, a rate of temperature change and a bias voltage.

Charge Pump Circuit Positive Voltage Output Pin 2

Connect to VSS2 with a 2.2

μF capacitor that should have the low ESR (Equivalent

Series Resistance) over all temperature range. When this capacitor has the polarity, the

positive polarity pin should be connected to the VSS2 pin. Non polarity capacitors can

also be used.
