Update: 01 October, 2023
The TPS2046 and TPS2056 dual power-distribution switches are intended for applications where heavy capacitive loads and short circuits are likely. These devices incorporate in single packages two 135-mΩ N-channel MOSFET high-side power switches for power-distribution systems that require multiple power switches. Each switch is controlled by a logic enable compatible with 5-V and 3-V logic. Gate drive is provided by an internal charge pump that controls 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 preset value, the internal circuit will cut off the output, and the overcurrent protection circuit will generate an interrupt signal.
