ESD protection

All TPS2202AI inputs and outputs incorporate ESD-protection circuitry designed to withstand a 2-kV

exposed to potentially higher discharges from the external environment through the PC Card connector.

Bypassing the outputs with 0.1-

µF capacitors protects the devices from discharges up to 10 kV.
