SP3220E
Key Features
- The SP3220E device has a highefficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation
- This charge pump allows the SP3220E device to deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V
- The ESD tolerance of the SP3220E device is over +15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods
- The SP3220E 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
