Product Summary
The TPS2046AD is a power-distribution switch. The TPS2046AD is intended for applications where heavy capacitive loads and short circuits are likely to be encountered. The TPS2046AD incorporates 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.
