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 70-mΩ 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 2.7 V.
