3 Description

The TPS206x power-distribution switches are

intended for applications where heavy capacitive

loads and short-circuits are likely to be encountered.

This device incorporates 70mΩ N-channel MOSFET

power switches for power-distribution systems that

require multiple power switches in a single package.

Each switch is controlled by a logic enable input. Gate

drive is provided by an internal charge pump designed

to control the power-switch rise times and fall times to

minimize current surges during switching. The charge

pump requires no external components and allows

operation from supplies as low as 2.7V.
