Figure 7-1 shows a MAX620 connected to power high-side switching and control circuits. The charge pump delivers a regulated output voltage that is 11 V higher than VCC to the drivers. In turn, the drivers translate a TTL/CMOS input signal to a noninverted output that swings from ground to the high-side voltage. The continuous driver-output current is 25 mA, with a typical quiescent current of 70 μA. The MAX620 requires three external charge-pump capacitors. The MAX621 has internal capacitors.
