The TPS2041A through TPS2044A and TPS2051A through TPS2054A power-distribution switches are intended for applications where heavy capacitive loads and short circuits are likely to be encountered. These 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. When the output load exceeds the current-limit threshold or a short is present, these devices limit the output current to a safe level.
The TPS204xA and TPS205xA series are intended for applications where heavy capacitive loads and short circuits are likely to be encountered. These 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, with gate drive provided by an internal charge pump designed to minimize current surges during switching. The charge pump requires no external components and allows operation from supplies as low as 2.7 V.
The devices support a maximum of 500 mA continuous current per channel.
These switches operate from supplies as low as 2.7 V up to 5.5 V.
The typical rise time for these switches is 2.5 ms.
