The SP3220EB/EU device has a high- efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3220EB/EU device to deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The ESD tolerance of the SP3220EB/EUE device is over ±15kV for both Human Model and IEC1000-4-2 Air discharge test methods. The SP3220EB/EU device has a low-power shutdown mode where the driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1µA.
