ESD protection
All TPS2205 inputs and outputs incorporate ESD-protection circuitry designed to withstand a 2-kV
human-body-model discharge as defined in MIL-STD-883C, Method 3015. The V
CC
and V
pp
outputs can be
exposed to potentially higher discharges from the external environment through the PC Card connector.
Bypassing the outputs with 0.1-
μ
F capacitors protects the devices from discharges up to 10 kV.
