DESCRIPTION
The TPS2090, TPS2091, and TPS2092 dual and the
TPS2095, TPS2096 and TPS2097 quad
power-distribution switches are intended for
applications where heavy capacitive loads and short
circuits are likely to be encountered. The TPS209x
devices incorporate 80-mΩ N-channel MOSFET
high-side power switches for power-distribution
systems that require multiple power switches in a
single package. Each switch is controlled by an
independent 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 2.7 V.
