Product Summary
The TPS2021IDRQ1 is a power distribution switch intended for applications where heavy capacitive loads and short circuits are likely to be encountered. The TPS2021IDRQ1 is 50-mW N-channel MOSFET high-side power switch. The switch is controlled by a logic enable compatible with 5-V logic and 3-V logic. 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.
