TEXAS INSTRUMENTS TPS2041B TPS2042B TPS2043B TPS2044B TPS2051B TPS2052B TPS2053B TPS2054B handbook
The TPS204xB/TPS205xB family consists of current-limited, power-distribution switches intended for applications with heavy capacitive loads and short circuits. These devices incorporate 70-mΩ N-channel MOSFET power switches controlled by logic enable inputs to manage multiple power sources in a single package.
The internal charge pump design controls rise and fall times to minimize current surges during switching, requiring no external components. The chips feature accurate current limiting, thermal protection, undervoltage lockout, and deglitched fault reporting to ensure safe operation from 2.7 V to 5.5 V supplies.
