TPS2091 描述

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-m 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. When the output load exceeds the current-limit threshold or a short is present, the TPS209x limits the output current to a safe level by switching into a constant-current mode, pulling the overcurrent (OCx) logic output low
