Overview
The TPS2042BDGNG4, produced by Texas Instruments, is a dual, current-limited power-distribution switch designed for applications requiring multiple power switches in a single package. This device incorporates 70mΩ N-channel MOSFET power switches and is particularly suited for systems that may encounter heavy capacitive loads and short circuits. The TPS2042BDGNG4 features an internal charge pump that controls the power-switch rise and fall times to minimize current surges during switching, and it operates from supplies as low as 2.7V to 5.5V. The device also includes thermal and short-circuit protection, ensuring reliable operation in demanding environments.
