Input Schmitt Triggers
All the Logic Input pins have built–in Schmitt trigger
circuits to prevent the NCN6010 against uncontrolled
operation. The typical dynamic characteristics of the related
pins are depicted in Figure 8.
The output signal is guaranteed to go High when the input
voltage is above 0.70*Vbat, and will go Low when the input
voltage is below 0.30 * Vbat.

Charge Pump Converter
The converter uses a switched capacitor technique to
increase the SIM_VCC voltage up to 5.0 V from a 3.3 V
typical battery. The concept, depicted in Figure 9, charges
the transfer capacitor C1 up to the Vcc value, then connects
this capacitor is series with the input voltage–output
reservoir network. The voltage developed across the load is,
theoretically, twice the battery voltage, but the system must
takes into account the losses associated with the power
switches and the internal ohmic drops.

Figure 9. Basic Charge Pump Converter
When the output voltage is programmed to 3.0 V, the
clocks are inactive and the load is directly connected to the
battery by means of switch S5. The SIM_VCC voltage
follows the input value, minus the drop coming from the
internal resistance . The current is limited by the Ron of the
power device S5 and t he output voltage will decrease as the
load current increases above 20 mA (typical). Figure 10
illustrates the theoretical waveforms.
