Function
Positive Charge Pump Capacitor Terminal Pin 2
Connect to CN2 with a 2.2μF capacitor that should have the low ESR (Equivalent
Series Resistance) over all temperature range. When this capacitor has the polarity, the
I
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 2.2μF +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 2.2μF capacitor that should have the low ESR (Equivalent
Series Resistance) over all temperature range. When this capacitor has the polarity, the
O
positive polarity pin should be connected to the VSS2 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 2.2μF +20% and -40% including the
difference by a tolerance, a rate of temperature change and a bias voltage.
- This pin should be connected to VSS1.
