SINGLE-SLOT, PARALLEL INTERFACE POWER SWITCH
FOR LOW POWER PC CARD SLOTS

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
APPLICATION INFORMATION
ESD protection
All TPS2212 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 VCC and VPP outputs can be exposed to po-
tentially 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.
